On Thursday a radical Islamic terrorist plowed a rental van into a popular pedestrian area teeming with tourists in Barcelona, killing 14 people and injuring at least 100 more.

Trump claimed that he didn`t immediately condemn the white supremacist domestic terrorists who murdered a woman in Charlottesville last weekend, because all the facts weren`t in yet.

Within an hour of the Barcelona attack, our national embarrassment of a president, Donald Trump posted this inflammatory tweet:

Study what General Pershing of the United States did to terrorists when caught. There was no more Radical Islamic Terror for 35 years!

Trump was referring to the myth (fake news) that General John Pershing dipped bullets in pigs` blood before ordering his soldiers to execute Muslim insurgents following the Philippine-American War in order to deter the insurgency campaign.

This myth has been debunked by historians, Snopes.Com and military leaders outraged at this lie that tarnishes the reputation of Gen. Pershing.

But let`s say it`s true, Trump is condoning a grievous war crime. To summarily execute war prisoners is an outrage, and keep in mind that the Muslim soldiers fighting Pershing weren`t terrorists, they were freedom fighters battling a colonial power that had invaded their nation.

Trump`s intemperate and false tweet is going to inflame tensions throughout the Muslim world, putting American tourists, diplomats and military personnel in danger.

Once again Trump has demonstrated that he doesn`t have the wisdom and moral authority to be President of the United States. Impeach the bastard!
