Consider Mr Darweesh. It took him three years to get those visas. He needed confirmation from the US embassy that his life was indeed at risk before he could even make an application. There were background security checks and medicals.
All this for a man who had spent a decade working for America as his homeland exploded in violence. A man who was more likely to be a victim of terrorism than a perpetrator.
That this approach is likely to prove counterproductive is a no-brainer. Isis and al-Qaeda recruiting sergeants have the all proof they need to argue that the US is at war with Islam.
And then there is the waste of America’s soft power. In my 12 years of experience travelling through the Jihad zone that runs through the Middle East from Libya in the west to Afghanistan and Pakistan in the east, one thing is constant: the fervour with which American flags are burned by populist leaders is matched by the energy ordinary citizens spend in seeking a route to America’s promised land.
A green card is the best way to a new life. For every anti-Western rally I have reported on in Khartoum, Mogadishu or Islamabad, I have dozens more requests from the residents of those places asking for help with a visa.
The lure of a wide-screen TV and a trip to Disneyland is a powerful antidote to the mullah’s call. Take that away and there are more destructive ways to find a personal nirvana.
And Mr Trump should think about what it means closer to home.
His election was built in part on his promise to restore the American Dream, rebuilding the contract with ordinary people that a hard day’s work should be met with a fair day’s pay.
But there are other informal contracts. Like the idea that serving in the US military is a means to attaining American citizenship. That creed and colour should be no barrier to success.
