Adolf Hitler’s 1938 threats to, and eventual occupation of, Czechoslovakia bore some similarities to what is now happening between President Putin and Ukraine.
In 1938,Hitler exaggerated, and stirred up, grievances over language rights in the German speaking part of Czechoslovakia. He directed the local German speaking leaders inside Czechoslovakia to ensure that they did not reach any settlement with the Czech Government. He used the lack of an internal settlement as a basis for seeking to incorporate these areas in Germany, under the pretext of protecting the rights of the German speakers.
Western leaders tried to mediate and negotiate without success, culminating in the showdown at Munich, where Chamberlain abandoned Czechoslovakia in return for piece of paper signed by Hitler and himself in which both agreed on “the desire of our two peoples never to go to war again.”.
Eventually, when Hitler broke his word and occupied the whole of Czechoslovakia in March 1939, trust broke down completely.
Hitler tried the same game with Poland in August 1939, possibly thinking he would get away with it again and the British and French would again huff and puff but do nothing. If that was his calculation, he was mistaken.
The crisis over the Sudetenland in 1938 played out more slowly than the one over Crimea. Putin has acted with much greater speed. In the former case, there was even time for a British Commission of Enquiry, the Runciman Commission, to spend a few weeks studying the situation on the ground in the Sudetenland and reporting back to London.
There is another important difference between the situation of Ukraine and that of Czechoslovakia. France had a Treaty of Mutual (military) Assistance with Czechoslovakia, which had been signed in 1925, guaranteeing Czech borders. Britain had no such Treaty but was drawn in because of its strategic commitment to France. That is why the Czechs feel, to this day, a particular grievance about France’s lack of action in 1938.
In contrast, Ukraine does not have a military alliance with any western country. It is not a member of NATO, and has no Treaty based military guarantees of its borders.
But, since 1994, Ukraine does have a general guarantee of its borders from Russia, the US, and Britain, given in return for giving up its nuclear weapons arsenal. According to this so called Budapest memorandum, Russia, the U.S., and the UK confirmed, in recognition of Ukraine becoming a member of the nuclear non proliferation Treaty and in effect abandoning its nuclear arsenal to Russia, that they would,
This is hugely important, and creates a major moral obligation because one of the goals of global policy is to get countries with military nuclear capacity to give it up in return for guarantees. If such guarantees can be unilaterally abandoned without consequence, this strategy for opposing nuclear proliferation breaks down.
President Putin may feel that Russia should not have agreed to that memorandum in 1994. But it did. Hitler certainly felt the then German Government should not have signed the Versailles Treaty. But it did. Indeed, German negotiators had much less choice, in signing the Versailles Treaty in 1919, than Russian negotiators had in 1994, in signing the Budapest Memorandum.
There was no duress in 1994.
What is happening to Ukraine, and in a different way what happened to Libya, will make it more difficult to get nuclear armed regimes to give up weapons in return for guarantees, however solemn. This is not just a matter of international law. It is one of practical politics and global security, for everybody including militarily neutral countries, like Ireland.
Unlike Ukraine, the Baltic States, Latvia and Estonia, which also have Russian speaking minorities, are members of NATO and do have military alliance guarantees.
It will be the existential test for NATO, if Russia makes or carries out threats on Latvia or Estonia, similar to the ones it has carried out on Ukraine.
