You have anything to support your statement? Here we have Israel, alone, getting strafed constantly, while the rest of the western world dithers in alleged neutrality. There are some differences sure, but it's a reasonable analogy. Alternatively, you can call Israel the modern version of 1938 Czechoslovakia, with the disputed territories representing the Sudetenland, that works too.
Israel's troubles do not change the fact that Great Britain in 1940 is not an appropriate analogy. Nor is Iran Nazi Germany no matter how much it might like to be.
Czechoslovakia was betrayed when England and France refused to stop Germany from dismembering it. Nothing similiar has been done by Iran.
Great Britain was under Nazi air attacks in 1940. By then the Nazis had invaded Poland, taken over Austria, invaded Czechoslovakia, invaded France, invaded Norway, invaded Denmark, invaded Holland, invaded Belgium.
Iran couldn't invade my ass.
This is a stupid analogy and does not help in understanding the current or the past situation.
Your alternative is also inappropriate. Germany by 1938 had violated numerous provisions of the Versailles Treaty which was to control its conduct, Iran has not violated any treaty with its actions.
