Going by Trump's actions in first term, the "no wars" thing was the rare promise that was actually pretty believable.
Trump first term didn't start new big wars, and withdrew from e.g. Afghanistan (in a bullshit way, but still). Based on past actions, and yes because Trump promised it, I believed that Trump would be isolationist in his second term.
From https://en.wikipedia.org/wiki/Mediaite :
So not the most credible source you could imagine. But on the other hand, Wikipedia doesn't list any examples of Mediaite being fake news. And in this case, Mediaite is just summarizing a CBS article - the CBS article should obviously have just been linked instead.
In any case, it seems to me that Trump has two options: 1) Give consessions to Iran to save the global oil market or 2) ground invasion. Since I can't imagine Trump surrendering, no matter how game theory rational it would be, I am expecting ground operations.
