Like the tea drinking surrender monkeys that ran away at Dunkirk, or surrendered Singapore to a force of 1/3 their size? Like that?
Dunkirk was a strategic retreat. No surrender there. Singapore was indefensible without adequate air and naval support. In neither case was Britain defending its home turf.
Had the American Army been in Northern France in 1940, the Krauts would have handed us our asses just as easily as they did the Brits and French. Had our Army been in Malaya in early 1942, the Japanese Army would have kicked our asses, just as easily as they did the Brits. Remember our great naval Victory at Pearl Harbor: 4 battleships sunk,4 battleships damaged, 12 other ships sunk or damaged, 188 aircraft destroyed, 159 aircraft damaged, 2,335 killed, 1,143 wounded. All of this damage at the cost of 29 Japanese aircraft and crews. Like that?
