How will the US respond to Iran increasing its enrichment levels?

With more bluster but also with the hope that they can eventually get the Iranians to the table. You know the more the Iranians actually escalate the easier it is for them to eventually engage in negotiations with the Americans. That is the silver lining in what's been an increasingly ominous nuclear cloud.

Will the new Greek PM have an easier time than his predecessor?

Well sure, in the sense that the Greek economy is now doing better than it was a couple of years ago. They've already had suffered from massive austerity. And you know he gets the benefit from that hard work also because he's more business oriented, he's liked by the international community, the IMF, the Germans. But still you're talking about 40% unemployment, massive lag in infrastructure real challenging economies, so one of the tougher places to govern certainly in Europe. No question there.

Does China see US-Australia war games as a threat?

I wouldn't say a threat. But not exactly an opportunity. Look generally speaking, the Chinese are putting a lot more money, and a lot more effort into expanding their territorial influence in the South China Sea. When they see the Americans, the Australians, even the Japanese, engaging in maritime exercises their response is going to be more bluster that includes spy ship watching closely steaming towards Queensland right now. Let's watch to see what happens.
