The political climate in the UK in 1937-38 was also submissive, but remember what happened the next year.
In the years since then; the 'Left' has diligently been about divide and conquer here at home and altering the mindscape of America - political correctness, being it's best tool. Our united resolve post 9/11 lasted but a few weeks; and then the Left began their work. Believe it has been the Left's determination since WWII that America - as in a Capitalistic America; would never again be indisputably victorious in any war against a Marxist enemy. Vietnam was in fact, 'their' victory. And they want/need. . . Iraq, to be theirs as well. The Democrat Party of 'now; because of it's 'Leftist'/Marxist ownership; is not only invested in defeat of America i.e. Capitalism; but committed to it. They want to recreate America in their nanny/totalitarian, anti-capitalisic image.
Meantime, around the world, including America; appeasement of radical Islam is not just in the air. And as Mark Steyn, notes the truth by way of demographics; the 'hand that rocks the cradle, rules the world'. . .It goes beyond demographics, of course; and is why Hillary so desperately wants the 'village' to raise the children; and why Liberals et al; knowing the power of the 'hand' as in the right education for raising the next generation; are today, feeling empowered as they are beginning to see results of their determined patience.
Right now, the 'Left'/the Dems. . .and the enemy jihadists; are two hands clapping. Can only wonder, should it become 'one hand clapping'. . .whose it will be.
