I doubt if Obama will prove willing to rethink America's role in the world. He is wedded to the linked concepts of the USA being the "exceptional nation" and being, therefore, at the epicentre of a unipolar world.
The world is turning away from these erroneous concepts and forging ahead with a world without the "west". Consider the energy deals recently entered into by China and Russia, the vibrancy of the Shanghai Cooperation Organisation and the entire concept of the New Silk Road linking China, Central Asia, Russia and, when they pull their heads out of the sand the US and NATO have recently kicked up, Europe. Those still espousing the Anglo-Zionist unipolar mind-set will have only themselves to blame for their coming redundancy.
And in Australia, we now have a PM so clueless as to extend an invitation to Petro Poroshenko, the President of Ukraine. This means we can look forward to a state visit from a man many consider to be at the heart of a government of reconstituted Nazis. This will not be a good look.

no nation or empire in human history has ever proven to be an "indispensable" nation: such a notion is the height of hubris, whereas a rethink of a nation's foreign policy requires a certain amount of humility to see itself as others see it.
I don't remember the British ever referring to themselves as 'indispensable':
a civilizing influence, perhaps, but never a state that others simply could not do without.
And by relinquishing their empire gradually and (mostly) peacefully,
they showed they had enough humility that their day in the sun was over.
There are still a few places to go, eg Gibraltar, but their legacy will endure.

Dear Brenden O'Connor.

It does not surprise me that one source of your anti US hatred comes from watching fictional plays where far fetched conspiracy is presented as fact. Nor does it surprise me that the artistic caste who are unable to create plays and movies that Australians want to watch, and who continually cry out for government arts grants, are born again socialists who want the government to own and control everything.

About the only thing you got righ,t was that Vietnam was a mistake. Given what happened to North Korea, it was an understandable mistake, but it was a mistake. However, I don't consider myself to be a Pope or a Brenden O'Connor who's judgement is infallible, so I don't go around in a pose of endless moral outrage wagging my fingers at those who through good intent occasionally get things wrong.

You forgot to mention that Kosovo was a US mistake also. The western world is now at war with Islam and the yanks should have been helping the Serbs drive the Muslims back into Albania.

Now "you may not be interested in war", Brenden, but as your hero Lenin once quipped "war may be interested in you." Whether you like it or not, the Islamic world has finally figured out that it has fallen right behind the modern world when it comes to providing a decent living for it's people. And just like so many dysfunctional minorities it is blaming everybody else for its woes instead of reforming it's violence endorsing and misogynistic religion. Today's Jihadis seriously think that Islam can not become ascendant until it kills every damned infidel in the world, and that includes you, Brenden. You had better start figuring out who's side you are supposed to be on. It's a no brainer, really.

Why Islam failed is a worthy topic for a supposed social progressive to focus upon. But as usual, today's guilt ridden and self loathing educated caste prefer to focus upon attacking the Americans. But it's safer that way. If you criticise Islam, they may just kill you.
