Beginning in the late nineteenth century, many began to dream of an international order based on peace and law. The United States government took the lead in some respects. The US government claimed a very large indemnity from Great Britain for shipping losses at the hands of the Confederate raider Alabama, and it submitted it to arbitration, with British consent,. and won a large award. It signed numerous treaties with foreign powers promising to submit other disputes to neutral arbitration. The same impulses led to the creation of the League of Nations after the First World War and the United Nations at the end of the Second World War. Both institutions attempted to ban aggressive war, leading self-defense as the only legitimate reason for conflict.
Atomic weapons posed new challenges. In 1946 the US government proposed at the new United Nations that they be banned, with atomic facilities put under international control, but the USSR refused the offer and developed its own atomic weapons instead. That led to high-level discussions of a possible preventive war in the United States. The US government regarded the USSR as a totalitarian nation bent on world conquest, like its enemies in the Second World War. That war had taught some that only total military defeat could remove such a threat. Cooler heads prevailed, however, and the US government eventually concluded that nuclear deterrence could keep the peace among heavily armed adversaries. By the mid-1950s, nuclear weapons had become the only real guarantee of a nation's sovereignty, and Britain and France were developing them as well. China followed suit in the 1960s and has now been joined by India, Pakistan, and North Korea. And Israel had apparently developed atomic weapons sometime during the 1960s, although the Israeli government never seems to have tested one and has never formally admitted possessing them. During the 1960s the Soviet Union and the USSR also tried to restrict and even eliminate nuclear weapons by negotiating the Nonproliferation Treaty. Non-nuclear signatories to the treaty (which some states refused to sign) promised not to develop nuclear weapons, while nuclear states promised to work to eliminate them. Although the US and the USSR drastically reduced their arsenals after 1989, Ronald Reagan was the only president who seems to have shared that goal, and he never took concrete steps to make it happen.
Israelis created the State of Israel in 1948 despite the hostility of Palestinian Arabs and neighboring states. Although they held their own in their War of Independence and decisively defeated enemy armies in 1956 and again in 1967, they too apparently concluded that they needed atomic weapons to safeguard their independence. According to some accounts, the Israeli government was preparing to use them in the early days of the 1973 Yom Kippur War, when things were going very badly on the ground. Instead, they regained the initiative on the battlefield. In one key respect, however, the Israeli government attitude towards nuclear weapons has differed from that of the two original superpowers. Rather than rely on their own nuclear weapons for deterrence, they have concluded that they cannot allow any hostile nation even to develop them either. Many years ago I read that the Israelis had assassinated Egyptian nuclear scientists, and French authorities apparently suspected that one such assassination had taken place in France in 1980. Menachem Begin's government unilaterally destroyed an Iraqi nuclear reactor in 1981. Israeli governments claim a right to take any military action necessary to stop a hostile nation from developing nuclear weapons.
The US government adopted the same view under the George W. Bush administration. A new National Security Strategy declared that the United States would take preemptive military action to stop any dangerous nation from developing weapons of mass destruction, and the Bush Administration justified the invasion of Iraq in 2003 on those grounds. I heard from well-informed people that they had planned to do the same in Iran and North Korea, but such plans went on the back burner, apparently, when it turned out that Iraq wasn't developing nuclear weapons after all. Successive US administrations declared that Iran must not be allowed to develop a nuclear weapon, and during the Bush II and Obama administrations, when Iran was developing the capacity to enrich uranium, the Israeli government pressured Washington to make a joint attack to destroy its nuclear facilities. In 2008, as I discussed here, the Israeli historian Benny Morris called upon the US to join Israel in such an attack, and threatened that Israel might have to use nuclear weapons of its own to destroy the key Iranian facilities if Washington did not join in. Washington apparently refused, and eventually the Obama administration joined Russia, China and the EU and negotiated a deal under which Iran limited its uranium enrichment to levels that would not allow it to build a bomb in return for the lifting of economic sanctions, In a sign of things to come, Republicans unanimously opposed that agreement, and Mitch McConnell invited Israeli Prime Minister Netanyahu to address Congress opposing the agreement. When Donald Trump came into power he withdrew from the agreement, and Iran ramped up its enrichment again.
Israel's conflict with Iran, its Hezbollah proxy in Lebanon, and its Hamas ally entered a new phase after the Hamas attack of October 7, 2023. To begin with, the Israeli government apparently decided to respond to that attack by making the Gaza strip uninhabitable and driving out most of the Palestinian population, as leading Israeli officials now admit. It also escalated the rocket war against Hezbollah, apparently with considerable success. And now, after two months of new US negotiations failed to reach agreement with Iran, it has launched pre-emptive strikes on that nation (its own words) to try to destroy its nuclear capability. Iran has retaliated promptly with salvos of ballistic missiles. I do not know whether Israel can achieve its military objective of destroying Iran's enrichment facilities, some of which are buried deep underground. As of today, only 24 hours into the operation, it has not tried to hit the Iranian stockpile of already-enriched uranium. In contrast to the attack on Iraq, however, it has hit targets in Iran not related to the nuclear program, such as energy installations and apartment buildings. Why is not clear.
We do not know how far Israel is willing to go--a critical question since Israeli governments have apparently talked about using nuclear weapons against Iran in the past. The Israeli government may be hoping to induce the US government to give it its most powerful bunker-busting conventional bombs to use against Iranian facilities by threatening the use of its own nukes. It may also hope that these initial strikes, and perhaps more strikes on Teheran itself, might convince the Iranian government to give up its nuclear program altogether, as the Trump Administration has been asking it to do. President Trump has just announced that he would like to see the war stop now, but he does not seem at all likely to force Israel to stop it. The US government evidently knew that the Israeli attack was coming and did not try to stop it. The Trump administration has also hinted that we might join in the defense of Israel.
This much is clear: the dream of a world ruled by law and diplomacy has faded into the background. Human nature being what it is, it never had much chance of success, but such dreams remain essential, I think, to keep humanity headed in the right direction. The end of the Cold War, it turns out, has moved us in the wrong direction, feeding US and Israeli dreams of world or regional hegemony imposed by force, and Russian and Chinese dreams of regaining lost territories. Israel has revived the project of using force to prevent hostile states from acquiring nuclear weapons, rather than relying on deterrence. The Israeli people seem to support that policy. We don't know where it will lead.
