Far more importantly, this might force Trump to continue the pressure on the Israelis, whose very nature is to be untrustworthy, not worth trusting, since they love not just violating agreements but also using agreements as a lever for abuse. There are all the typical Israeli fingerprints all over the current deal that the Israelis will likely use to bring the whole thing back down around Trump unless he can maintain pressure. This prize increases the slim likelihood that he will have to of he covers that prize as much as it seems he does. I do not think he can or will though, and the Israelis may just even persuade him that they have a far more juicy prize to offer him instead.
I think Trump wanted to force the rather compromised committee to make a similarly foolish decision as giving Obama the prize, which would have then permitted immediate Israeli breach of the settlement.
Not to take away from Machado’s work, but this year’s prize is at the very least political, to both appease Trump in line with the above and also send a message in the face of the war build-up against Venezuela. At the same time their decision also facilitates the American takeover through less than lethal means by CIA revolution and the combined pressure of it all on the Venezuelan government. Machado is in fact a CIA asset, whether she realizes it or not.
