Trump's handling of military strikes/operations, which have been mostly symbolic. Killing Soleimani, and not retaliating to the retaliationary strikes. A completely useless strike on Shayrat airbase in Syria. Pulling out of Yemen strikes this year because it was ineffective (never admitting to this though). Trump wants to be known as a deal maker. I don't think that has changed, he's just become more delusional regarding the practicality.
