You might find it hard to believe, but there was a time when every war on the face of the earth was not considered to automatically involve us.
And while you have a case of the fainting vapors over Poland, you say nothing of Ethiopia. You think we should have intervened in Ethiopia when Italy invaded?
For perspective, Poland as a nation had existed about 20 years in 1939. From 1815 until Versailles in 1918, most of it fell it fell under the Russian Czars and under Prussian rule starting with Fredrick II.
In WWI 21 years before, 38 million people had died. America saw Germany and Russia invading Poland and disliked it, but basically saw it as restoring the pre WWI territory they had claimed for 200 years.
While Britain and France, had alliances, there was no way America was up for going to war over Poland. No more than we would have over Ethiopia.
And remember, you are looking at hindsight. Katyn was carefully hidden for a few more years. The holocaust was in its infancy and was also hidden.
Its bullcrap for you to say America did nothing.
You admitted we did nothing but justified it; I don’t even care that we avoided the war, but think we should reserve judgment of those who couldn’t.
Katyn was documented by the Red Cross as being perpetrated by the Soviets DURING THE WAR. They knew immediately (from the victims’ clothing) when it had happened, and told the world so at the time. Germany was the one who initially sounded the alarm, and 50 years later the USSR admitted they had done it.
