Donald Trump has already put his presidency on the line, by acting like Tony Soprano with the leader of Ukraine.

That phone call was a shakedown for a political favor, with a thinly-veiled threat to withhold foreign aid the small nation relies on to fend off Russian aggression.

Now, following another phone call between Trump and Turkey’s president, we are suddenly pulling back U.S. troops to make way for Turkey’s planned invasion to clear the Kurds out of the border zone in Syria.

It blindsided the Pentagon, and both houses of Congress: The Kurds were our strongest allies in taking back territory from ISIS. Yet Turkish dictator Recep Tayyip Erdogan considers them terrorists.

And astonishingly, Trump is now abandoning them to die.

It makes you wonder what exactly was said during that phone conversation, too. Trump is an admirer of strongmen, and has a lucrative property in Istanbul, one he’s acknowledged could affect his decision-making.

“I have a little conflict of interest ’cause I have a major, major building in Istanbul,” Trump told Breitbart radio during his campaign. “It’s a tremendously successful job. It’s called Trump Towers—two towers, instead of one, not the usual one, it’s two.”

We withheld hundreds of millions of dollars in aid from Ukraine, potentially because Trump wanted the country to dig up some dirt on his 2020 rival. Are we now allowing Turkey to come in and massacre the Kurds, because of his business interests?

We don’t know, and that’s the point. We can’t even trust our own president to put America’s interests first. It’s like Trump’s telling take on Saudi Arabia: “They buy apartments from me,” he said. “They spend $40 million, $50 million. Am I supposed to dislike them? I like them very much.”

He's been hiding his tax returns that might reveal other foreign connections that influence his policies. He’s been churning up business for his hotels after the Group of 7 summit of world leaders, suggesting its next location should be – where else? – his luxury golf resort in Florida.

The House is currently investigating whether foreign officials tried to curry favor with Trump by booking rooms at his hotels but never staying in them. And was it pure coincidence that Ivanka got more than a dozen trademarks in China while he was in trade talks?

This betrayal of the Kurds isn’t just a dishonorable outrage. It has real national security consequences. It undermines our ability to get other allies to fight with us, because they don’t know if we’ll turn on them.

And it puts us in potential danger. This doesn’t mean we’re quitting Syria altogether, where we still have about 1,000 troops, and bringing Americans home, as Trump has suggested. Right now, we are simply getting out of the way of any Turkish attack.

If Turkey crushes the Kurds, and the tens of thousands of ISIS fighters they are holding prisoner escape, they could return to being active terrorists who might attack us, particularly our troops still in Syria.

Meanwhile, we are left to question the motivation behind Trump’s decision. Is this about the lives of Americans and Kurdish people? Or protecting a business partnership with Turkey worth millions to him?

We shouldn’t have to wonder. Yet until Trump releases all his tax returns, and divests from his global businesses, this will always be an easy way for a foreign official to exert leverage on him – much like he’s accused of doing with Ukraine.

Thanks to Trump’s personal history of grift, the message to our allies across the globe is clear: The blood you shed for America means nothing. Come back when you’ve got something lucrative to offer him.
