Liberals are complaining that we should never have extended NATO so far east, because it upset Russia in general, and Putin in particular. Just how many East Block countries would liberals have left to the not so tender mercies of a resurgent Russia? It seems clear to me that a policy of appeasement always fails, and that a policy of appeasement is what liberals recommend. Their complaint implies that we should have left Latvia, Lithuania and Estonia out of NATO. If we had, these Baltic countries would have been overrun by now.
