Well, Popeye I would say that the belief that the US cannot take casualties has historically been a massive miscalculation. In both World Wars, Germany (certian generals in WWI, Hitler himself in WWII) dismissed US invlovement, believeing that the US was not wholeheartedly in the war and that they would drop out after one defeat. Yamamoto understood better, but still believed that the US would give in after enough bleeding and if Japan scored a quick string of victories. Kim Il Sung never thought that the US would make a stand in Korea once they realized the scale of operations it would entail. Even Saddam and Osama Bin Laden both believe/d that if they inflicted some casualties it would cow the Americans. All of them were wrong.
The key turning point is when the American public believes they are in an effort that is losing and/or not worth it and without a clear objective. Witness Vietnam and Iraq.
Just elaborating on my thoughts.
Man... All yr examples r horribily wrong! WWII? Japan give US a surprise attack which cos such outrage that all American determine to fight. If US don fight,aren't they going to be annihilate by Japanese? Hitler is a partner of Japan and Axis power. Definitely ,US had to fight all way. US don have a choice. It is either u die or me.
In Korea War,US never expect Chinese to enter the war. They thought North Korea was easy meat. A terrible wrong calculation,they never expect they got a big brother call PRC. Btw,Chinese also not interested to escalate the war that they continued to intrude into South and fight. The last 2 yrs of Korea war was more of a border fight which slowly dies off.. If PRC decided to fight all the way and drag it for another 4-5 yrs,more or less,it will be the first Vietnam war for US and US will withdraw...
The last one makes me laugh even more! When did Saddam forces inflicted the so called "Some casualties" on US forces in conventional warfare? Less than 100 men killed in Gulf War 1,not to mention GUlf War 2? Who u trying to kid? Saddam estimated his forces will inflicted heavy casualties on US forces but never achieved that. Imagine more than 8000-10000 men killed. See what will be the outcome?
When did Taliban inflict heavily casualties on US forces in conventional Warfare?
Let me ask u another question? Isn't the insurgent of Taliban and Iraq inflicting high casualties that US opinion of Iraq war becomes unpopular? In fact,it is only less than 3000 casualties but....
Another question. How Republican lost the congress recently?
How US going to be united to fight for ROC(A province of China) if a high chances that many American lifes going to be taken? It is a war which US can chose not to fight or fight without any effect on them. Unlike WWII
Please give me better reasoning and examples...
