That is your opinion. These countries have capable armies.
US benefits from NATO in a different way; it gets unprecedented level of access and control of airspace and land. It is a military and political power benefit, much more precious than some joke money. US can print all the money it needs, since US dollar is reserve currency.
As far as I'm aware the country where I live - and plenty of others - have contributed to various NATO exercises, budgets, weapons spending and in fact combat missions.
If you think that it was 'too little' then that's fine with me but it still does not align my world view with that of the neocons or any other American political organization. The world is a little bit more complex than that.
The Bush administrations reasons for interfering in Iraq had absolutely nothing to do with Iraq threatening their neighbors, you really should read up a bit on that particular chapter if you want to start arguing about it. And in spite of all the bullshit that led to that particular war there - again - were plenty of people from countries besides the US involved. Though, it has to be said, not at the same level but this in part had to do with the fact that the evidence that led to the Iraq war was about as dodgy as it gets.
