How will the U.S. respond to Iran increasing its enrichment levels?

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.

Does Boris Johnson strengthen or weaken the US-UK relationship?

Well I mean strengthens it in so far as he and Trump like each other. They're both oriented towards Brexit. They're kind of right-wing populists that aren't ideologically moored. But will it last? Boris could flip on a dime on any major issue as can Trump. So it's kind of volatile. Plus they both really love the media and when they're in front of each other with other people the potential to - I mean Boris upsets people and Trump easily takes offense. So this could easily go south.

Will Iran release the captured UK oil tanker?

I mean over time I suspect it will. But remember the UK has an Iranian tanker as well, so it's much more likely they work these things out together even if they're not explicitly linked, than suddenly the Iranians say, "Oh I'm sorry. Here's your tanker"

Will protests continue in Hong Kong?

It certainly seems that way. The question is what will China do about it? Xi Jinping is now saying that they are reaching the danger zone and the ability of the Chinese to hit back and hit back hard is real. I worry about those protesters.

Will Robert Mueller reveal anything new when he testifies on Capitol Hill?

I highly doubt it. He said very clearly that he does not intend to go beyond what was in his report. So Democrats looking for bombshells on collusion or obstruction are likely to be disappointed.

Can President Trump expand his electoral college edge in 2020?

Well he thinks he can. He thinks he can win in places like Minnesota and New Hampshire. I think it's more likely that he just hangs on to the Rust Belt states like Pennsylvania, Michigan and Wisconsin that got him there in 2016.

Should the governor of Puerto Rico resign?

Finally for The Rant: today's rant is on Elizabeth Warren who put out a report today saying the economy is on the brink of collapse. It was very alarmist, certainly there are problems with the economy. Issues that could be fixed but she risks sounding like she's yelling fire in a crowded theater with calls like that.
