Your mistake is that you think in 2D, Trump thinks in 3D...
Not even sure what this really means. I know of zero 2D thinking in our 3D universe.
We are all 3-D thinkers since that is what we live in. a 3D world.
If you honestly believe he'd just walk away "willy nilly" then you simply don't understand the situation...
He is placing an opening position in a negotiation, you never open with the "reasonable middle option", because you'll be forced to move from that. He starts with a far off position and works towards the middle.
Perhaps you could be correct, but I think it is either very transparent bluster on the part of Trump that will soon be found out for what it is... nonsense. Either that or it is in fact Trumps expression of wanting to move in a more isolationist manner with the US. To me it seems that neither is actually all that effective behavior for a Superpower. We must keep our big boy pants on and man up to our role in the world. Superpower adults don't whine and throw fits.... 3 year olds like North Korea do.
Is it I who don't understand the situation? Or is it you? I'm not sure you are privy to Trumps thoughts any more than anyone else... but if you think you have a bead on the situation or are able to divine what Trumps thoughts truly are, then go ahead an believe what you will. I am just dubious. He spends a lot of time saying what people want to hear in many contradictory directions. He is a man of the moment and a man of fluctuating mood. He will say what is on his mind now and may say something entirely different when his mood changes.
I view Trump as a simpleton in the matters of nations.
Being a businessman does not make a person de facto good at governance of a Nation. A nation and a business are not equivalent entities. A business can be run much more top down than can a republic. In a business, the vision and guidance of the owner of said business determines the direction the business goes.
Anyhow... you apparently like Trump from your lauding of his amazing 3D thought process. From my perspective, I suspect he would be a horrible leader. Never has someone with so little understanding of the governance of a Nation been on the cusp of being elected to a post he is so ill equipped for. The US has never elected a president with no experience in the political arena. Franklin would likely be appalled.
However, if Trump is elected which he could easily be, it will make for some interesting times. He will likely be displeased with constantly having to tussle with an unruly legislative body that is likely to give him nothing but grief. I'm sure he will revel in how powerless the president really is. He will have to rely on a lot of people to get things done because he really won't understand much of it. But empty vessels such as him will get filled up by someone. The nation will move forward no matter who is elected.
Hopefully, will Trumps election be of benefit to our Republic and for the betterment of the lives of all of our citizens. Or will he like all elites push for laws which benefit primarily those like him? I think his is likely to push for things that benefit him the most and the debt of our nation will soar. It will certainly be an interesting roll of the dice.
I don't think either of the current candidates is very good and would rather vote no confidence. That way we could get some better options.
Gary Johnson for me is the most interesting candidate although he is also a bit of a question mark as to what he would do. I am interested in hearing more of what he has to say as the campaign wears on.
