SC, Yes, Trump could change, especially if the change is necessary for his own success. We'll be along for the ride, so here's hoping he can pull it off.
His cabinet appointees so far look like capable people. Webster Tarpley points out that while Trump wants better relations with Russia (a positive compared to Hillary), his attitude toward Iran could be more warmongering than Hillary's, and Trump's appointments so far appear to be hardliners on Iran. Tarpley warns that there's more than one way to stumble into WW III (besides Syria), and going after Iran again is fraught with big dangers.
Trump is friends with Netanyahu (as is Romney) and Trump actually made a TV commercial for Netanyahu during his Israeli election campaign. Obama attempted to be more even handed in the Israeli-Palestinian situation, partly from the influence of Brzezinski, and that made Obama very unpopular with many Neocons.
But it's unlikely the Neocons would do an actual attack on Iran until after Syria is neutralized, due to the 1000 Scud missiles Syria has. Syria and Iran are close allies and Syria's missiles are only ~10 minutes flight time from Tel Aviv. Israel has the 'Iron Dome' anti-missile shield, but it would be overwhelmed if Syria launched their Scuds.
That's what makes Syria so critical in the Middle East strategic chess board. The US wanted Assad out years ago but were stymied, and thus were forced into the Iran deal. The plan had been to remove Assad, then go after Iran, and then attempt regime change in (gulp) Russia. How they expected to pull this off without triggering WW III is another question.
So bottom line we'll just have to hope for the best. Like the song says - 'Skating away on the thin ice of a new day'..
