Over the weekend, a group of Arab American and Muslim American leaders in Michigan appeared onstage at a Donald Trump rally and urged their communities to vote for him. The outreach might be working: A recent poll showed Trump with a narrow lead among Arab American voters.

This is shocking, but hardly surprising. It’s shocking because Trump’s stated policies—on Palestine, on political freedom, and on the very presence of Muslims in America—are antithetical to so much of what most of these voters believe in. It’s unsurprising because we Arab and Muslim Americans have a long tradition of merciless political self-sabotage.

In 2000, angered by the sanctions against and bombing of Iraq, the use of “secret evidence” in deportation proceedings against Arab and Muslim immigrants, and especially the carnage of the Second Intifada, many liberal Arab Americans—myself included—decided not to vote for Al Gore and turned instead to Ralph Nader, himself a prominent Arab American. If the point was to advance Arab political interests, our protest was a pathetic failure. The election of George W. Bush led directly to the catastrophic 2003 invasion of Iraq, a strategic disaster that continues to resonate in the Middle East, and the deaths of hundreds of thousands of Arab civilians.

This time around, the primary grievance is the Biden administration’s support of—or, at least, inability to end—Israel’s invasion of Gaza and, now, its widening wars in Lebanon and Iran. Once again, the impulse is to express our anger and “punish” the politicians responsible by withholding a vote for them. In an election with only two viable candidates, however, there is no difference between not supporting Kamala Harris and actively supporting Trump. And a quick review of the most important issues on which there’s a consensus among Arab and Muslim Americans demonstrates that a second Trump term would be dramatically worse than a Harris presidency.

Start with Trump’s signature issue, immigration. Nothing in Harris’s agenda would restrict immigration from Arab or Muslim countries. Trump offers the precise opposite. One of his first acts as president was to institute a “Muslim ban,” flatly prohibiting the entry of nationals from a list of seven majority-Muslim countries. President Joe Biden rescinded that executive order; Trump has vowed to reinstate and possibly expand it.

Moreover, Trump’s likely attack on Temporary Protected Status, especially for Haitian immigrants, is ominous for a number of Arab and Muslim communities whose members currently qualify, including Afghans, Somalis, Yemenis, Syrians, and Sudanese. With a stroke of Trump’s Sharpie, all of them could find themselves stripped of this protection—and included in his promised “bloody” mass deportations. Efforts to extend Temporary Protected Status to Lebanese nationals, entirely plausible under a Harris administration, would be dead in the water under Trump. Defending his decision to endorse Trump, an imam in Michigan declared that the former president “promises peace.” He plainly does not. The Washington Post has reported that, according to six sources, Trump recently told Israeli Prime Minister Benjamin Netanyahu to “do what you have to do” militarily in Gaza, Lebanon, and Iran. The notion that Trump would prioritize the interests of Arab civilians is simply absurd. This is a man who has repeatedly used the word Palestinian as an epithet against his (in many cases Jewish) Democratic political opponents.

Trump already has a long, instructive, and highly discouraging record on these issues. As president, he moved the U.S. embassy in Israel to Jerusalem and issued a statement recognizing Israel’s sovereignty in the contested holy city. He recognized Israel’s annexation of the Syrian Golan Heights, in direct contravention of the United Nations charter’s rule against the acquisition of territory by war. And he slammed shut the Overton window on Palestinian independence and a two-state solution, which had been a matter of bipartisan consensus since the end of the Cold War. His “Peace to Prosperity” plan, released in January 2020, invited Israel to annex 30 percent more of the West Bank. Such a move would leave the remaining Palestinian territory surrounded entirely by Israel, and therefore incapable of meaningful sovereignty. The primary effect of this crude document was to create a permission structure for Republicans to support wide-scale Israeli annexation of the West Bank and dispense with supporting Palestinian independence.

Harris, by contrast, has been categorical in her support of a real two-state solution that would mean the end of the occupation that began in 1967. The vice president has clearly stated that Palestinians and Israelis need to reach a peace agreement that affords them “equal measures of prosperity and freedom.” Trump has never spoken of Palestinians and Israelis enjoying equal measures of anything.

Trump’s anti-Palestinian bias extends to the home front. Arab and Muslim Americans have been emigrating to the United States in large numbers since the late 19th century in search of a better life characterized by liberty and democracy. And yet Trump’s whole campaign, and his entire agenda, amounts to an assault on those ideals. He has consistently singled out pro-Palestinian protests on college campuses as part of a “radical revolution” that he has pledged to eliminate. According to The Washington Post, he told a group of Jewish donors in May that he is determined to deport pro-Palestinian students and “set that movement back 25 or 30 years.”

Our communities are overwhelmingly aghast at the U.S. government’s ongoing support for Israel’s military campaigns. I share the sentiment. But channeling that anger into support for Trump would be an exercise in the most rarefied gullibility and naivete. Far from promising peace, Trump threatens war on “the enemy from within.” Arab Americans and Muslim Americans, particularly those with pro-Palestinian sentiments, are likely to be high on the list of targets. We need to learn from the lessons of our own history. When we try to punish the politicians who have disappointed us without taking a serious inventory of the likely consequences, we usually just end up hurting ourselves.
