i hope you meant that as sarcasm...
The British and French ostensibly go to war over Poland after giving them a mouth full of promises sane men in Poland should have known would never be kept then FDR and Churchill handed Poland to the USSR on a silver platter.
I've read that DeGaulle objected but I've also read that his objections were all for show so I don't really know how the French saw the situation and couldn't have done anything about it if they did dislike things. Churchill gets a lot of credit for things he had no real say on, too, so the bottom line to me is that after the French and British shafted Poland FDR finished the job by making sure the 75% of the population that survived would be shafted for the rest of the century.
Poland has had more than a few delusions of grandeur over the centuries but the damn sure deserved better "allies" than they had in WWII. Personally, I don't think they're very smart to put much trust in the US, British, and NATO, even now.
But, hey, what do I know?
