If you have studied History what's happening in the Middle East and Ukraine reminds one of the late 1930s

Yes. If you study what happened with Hitler in the 1930s and match that to what Putin is doing now both in Syria, Crimea, Ukraine and potentially Estonia and other countries, it makes perfect sense that NATO countries are arming Ukraine now as a measure of self defense of their own countries now as well as defending Ukraine. Because if Putin gets all of Ukraine: "Why should he stop there?".
