Bill,

There have been periods in recent history where - mainly the liberal democracies - have been at a minimum puzzled and many have strongly opposed what the USA has pursued. Vietnam comes to mind, then the arrival of President Reagan, with what appeared to be dangerous policies, Star Wars and cruise missiles came to the fore, in Europe.

With the declared end of the 'Cold War' there was a shared perception it was a new world and a diminishing public interest in national security.

9/11 meant the USA had global sympathy, which has slowly ebbed as the 'Long War' has lengthened and the public has got nervous, even fearful of what may come. I doubt there is much public support within the "willing coalition" to commit blood and gold to Afghanistan.

There has always been a concern, maybe a fear, that the USA would simply 'put America first' and not be too worried about the national interests of allies, friends and others. President Trump has accentuated that.

One consequence, alongside many other factors, can be seen in the UK where a politician once regarded as on the fringe is now the Labour Party's leader and who historically has not been friendly towards the USA.

I would ask two questions in response: Does the USA listen to those who are allies and friends? Can they really have an impact today?
