From Trump late last year: 

"We don't want to have a depleted military because we’re all over the place fighting in areas that we shouldn't be fighting in. It's not going to be depleted any longer," he said.

"We will stop racing to topple foreign regimes that we know nothing about, that we shouldn't be involved with," Trump said.

Trump has been in office for less than 7 months and is boasting about war with North Korea and now Venezuela.
