It has nothing to do with villifying or taking sides.
It has to do with understanding the motives and the real reason for the action , we the public are being told by the heads of the state and how critical/sceptical/analytical  or in the contrary naive/simplpistic/short-sighted have become of evaluating it.
I dont think US or any other country in that sence would do ever anything other than what is the absolute minimum in any case to protect and promote their own interests FIRST.
The  fact we talk about the motives of US , is  that US at the moment , like many other countries in the past seems to have a slight advantage in power ,being that power economic or  military, and uses it accordingly as i stated above.
Thats fine and understantable , but when someone talks about bailing out (WW1?,WW2? ) and then milking it out for their own interest up to present , its called differently.Not something that i would nessesary condemn but not something i would hand out a metal either.Just the way of things and i can accept that.By the way , i think the term bailling out is a bit insulting to the rest of the participants in that effort , dont you think?Why is it the Americans think they won the war on their own ?I would say they helped a LOT more than anyone else probably but still everyone played their part to get there and probably again , everyone would have to. 
Unless you talking about another instand of bailing out someone without 
a)being fully or partly responsible for  it in the first place
b)taking or demanding something equal or more in return.
Never happened and never will.
You must be very naive to say the least to think that nations act uppon and from motives and notions like  humans in indivindual level do.Sacrifice , compansion, sympathy  etc.Empathy which is a key instict of the human  simply doesnt exist in that level.They do so only if it serves their interests which at our age they are  synonymous with profit and profit only.Recent example is the release of the Lockerby bomber from their closest allie in the world , G.Britain(American plane wasnt it?) which surprise surprise had everything to do with BP getting the oil from Libya--and to think that most victims were US sitizens --.And thats how much the current heads of the states , the big coorporate interests behind them and seemingly what we see as the nations that once helped the fight against facism , think of  and cherish  the values you talked about, in front of the opportunity for profit and also the realisation of the real needs of the todays society we have become.
Sad but true.And as i say this (A Greek) i am even more disgust with the mokery that democrasy has become of, not only in your country but even more in mine.US,Greece ,G.Britain as states have in my opinion very little in common in terms of values and character as they did 50 or 150 years ago.Borders today exist only on maps and money draws the real borders.
In any case as history shows we can talk about US today , but we were talking about Germany 50 years ago, G.Briain 200 years ago, Greeks 2000 years , simply bacause everyone seeks an opportunity to get at the top, and those who  do occasionally write the history of human kind as we know it.
