So the basic thrust of your arguement is US forces had self-exploding tanks, bombers who could not hit a beach, and generally incompetent leadership. I believe you also ranted about WWI helmets, ugly casualty rates, fire bombing of cities, atomic weapons and fearsome enemies flying bamboo airplanes.
So, if the US forces were as incompetent as described why do the WWII nations of Germany, Italy, Japan and USSR no longer exist?
Seems to me that despite all the faults, failures and just plain incompetence that you have so carefully located, the US soldier, sailor, airman and Marine simply kicked ass. Something about being willing to say "NUTS".
So my question still remains.
Why should the US protect Europe, Japan, Taiwan or Korea? Why should the US protect the Middle East oil fields when the majority of that product goes to Europe, Japan, and China? What does the US care if heating oil prices in Europe skyrocket?
If you really think the US is going to get involved in your WW3 scenarios, you better explain why the US will be interested.
Actually if oil prices in Europe skyrocketed due to being cut off for example the american based oil producers would simply prioritize selling to Europe. Free market and all that so of course they will sell where they get the most profit. Its also fun how you always expect that everyone wants your help and you base that on WW2.... when the whole world had to band together against Germany.... Which is in Europe.... And is currently a much nicer country then America ever was.... I honestly dont see a problem with the Atlantic Ocean being between us right now. Could perhaps have been wider but one can dream.
I gave you ample evidence on Americas lack of morals, leadership, preparedness, priorities, realistic view point and training. The fact that you exist and X country dont has nothing to do with your "greatness" and you just claiming it is outright childish. A country does not need to be successful or unique in any way to persist. Cant you see how silly you are going "haha we lived longer then youuuu"?
You claim that Germany, Italy and Japan does no longer exist? They are far greater now then they ever were. Who do you think is leading the world in stuff like Technology, economy and social development? Who the heck needs oil when we get our electricity from green energy combined with nuclear power plants?
I believe USA will be the one to START WW3. No one else seams to bother except some arab countries that have not had peace since they invented the stick.
