President Donald Trump said the US would be “starting” land strikes on drug operations in Latin America, though again declined to provide details on when and where the escalation of his military campaign would actually begin, or if countries could still do anything to avert the threatened action.

“We knocked out 96% of the drugs coming in by water, and now we’re starting by land, and by land is a lot easier, and that’s going to start happening,” Trump told reporters Friday in the Oval Office.
