'So what deal would he do with Putin? What if Putin doesn't fancy it, or reneges on the deal?'
I don't know. Putin will want a fair deal, he wants to get along and do business etc. Trump plays hardball and is king of the Art of the Deal, but Trump is also fair, he doesn't take all of the pie, he will do a deal that suits America and where America wins but where the Russians will also get something out of it. Putin will have no choice provided it is a fair deal.
'How will ISIS be cleared out of Syria in a manner which doesn't harm the rest of the population? '
Because you have to understand what Isis really is, what the London DJ Jihadis and Chechen rebels and former Saddam generals and all of the funded mercenaries really are. They have been helped and funded to act as a proxy army to take down Syria for Syria's Sunni neighbours. I think, but I don't know, that Trump will change the world, that the Sunni game will be over. He has said it looks like Turkey is helping Isis with the oil, he has said it is great that Putin is sorting Isis out, he has said that we don't know who we are backing in Syria and that although Assad is a bad guy, that some of the people we are backing seem worse etc. The Saudi prince called Trump a "disgrace". Roger Stone says that some Saudis have funded the Bushes. There is probably panic among some rich people about what will happen if Trump takes charge and changes everything.
'in a manner which doesn't harm the rest of the population?'
Our generals said it could be done in two weeks with ground troops and tanks. Everybody says that bombing won't beat Isis. I think Trump will finish them for real. He will get other people to do it, he will do deals to "get the job done" and above all, he will warn every single puppet in the region that if they are found to be funding Isis that they will be in big trouble. That will end Isis very quickly indeed.
'And when he tells other governments they'd better watch out, what is he going to do if they don't?'
This is where Trump says he wants to be "unpredictable". He doesn't need to spell it out. They are already in meltdown at a potential Trump presidency, they know what it means.
'Are we talking declarations of war here?'
No, Trump doesn't need to do that. All he needs to do is tell them hardball on the phone. If they are stupid enough to call him "unfit for office" after that, then they are more stupid than anyone thought. Trump can call for the sequestration of assets, accuse people of aiding and abetting terrorists, put sanctions on, put arrest warrants out and if necessary activate regime change. They know the game, they know that no one messes with Trump.
This is where what I think the faux conservative Fox host, Bill O'Reilly, is wrong. He keeps interviewing Trump and saying "but Donald you can't alienate these countries, we need their support to defeat Isis". Everyone knows, including Trump, that some of these people are actually funding Isis. And Trump says "don't worry about it, we are already paying lots and we get nothing, nothing, we lose everytime, we are run by losers". Trump knows that if he tells them the score, they better listen. If they are not on the side of America, then they are on the wrong side.
