President Donald Trump is being hammered on social media after claiming the Civil War “could’ve been solved” without more than 600,000 people being killed in the conflict.

Trump made the remark while opining on Israel’s strikes on Iran.

“I wonder if the Civil War — it always seemed to me it always could’ve been solved without losing 600,000-plus people,” Trump said.

The president did not elaborate on what his strategy would be.

He was mocked on social media over the remark, with some users referencing Trump’s unkept promise to end Russia’s war with Ukraine in 24 hours.

“If I was president, we would not have the Civil War … I would’ve ended it in a day,” one user wrote of Trump while using the clown face emoji.

Another said Trump’s claim was the result of the “simple, beautiful, unshakeable confidence of a complete f—— moron.”

“When he says this i truly think he is implying they could have just continued to allow there to be slave states and non slave states,” said a third.

Some users suggested Trump was implying he would have let the South continue to hold slaves.

“If the North had agreed to allow slavery in the western states and the South, there probably wouldn’t have been a civil war. Trump is a virulent racist and ignorant fool,” one user wrote.
