President Trump may be the alleged drug boat destroyer, but he has a long way to go before he tops the drone warrior.

Mr. Trump’s campaign against those he says are drug couriers is garnering headlines, but it’s also sparking comparisons to President Obama’s drone mission to kill people he identified as terrorist targets, including an American citizen overseas.

Mr. Obama’s death toll, figured to be in the high hundreds or even low thousands, is well above the 83 presumed kills from strikes on suspected drug boats, though Mr. Trump is quickly adding to his numbers.

Untroubled by the deaths, Mr. Trump said he is certain that those on the boats deserved to be killed.

“We know everything about them,” he said.
