Trump failed: His strike in Yemen was a disasester and it killed an 8-year old child

Five days into his presidency, Donald Trump ordered a military strike on an Al-Qaeda base in Yemen. Barack Obama refused to do it because the conditions for the strike were too poor, so the Pentagon asked Trump when they thought the conditions had improved. But according to The New York Times the raid was so poorly planned and executed it ended up being a disaster in which an 8-year old child was killed by US troops. I quote from the NYT article:

As it turned out, almost everything that could go wrong did. And on Wednesday, Mr. Trump flew to Dover Air Force Base in Delaware to be present as the body of the American commando killed in the raid was returned home, the first military death on the new commander in chief’s watch.

But there's more:

The death of Chief Petty Officer William Owens came after a chain of mishaps and misjudgments that plunged the elite commandos into a ferocious 50-minute firefight that also left three others wounded and a $75 million aircraft deliberately destroyed. There are allegations — which the Pentagon acknowledged on Wednesday night are most likely correct — that the mission also killed several civilians, including some children. The dead include, by the account of Al Qaeda’s branch in Yemen, the 8-year-old daughter of Anwar al-Awlaki, the American-born Qaeda leader who was killed in a targeted drone strike in 2011.

But Trump claimed the raid was a success because the US military captured “important intelligence that will assist the U.S. in preventing terrorism against its citizens and people around the world.”

Which begs the question: Why would Al-Qaeda continue with their plans if they know the US have their information? Didn't Trump used to say that it's better to use the element of surprise? Why is he telling Al-Qaeda that he has their information then? Where's the element of surprise in that?

So in the end, Trump's raid was, to use his own words "a disaster."
