Re “Turkey Begins Syria Offensive, Targeting U.S.-Backed Kurds” (nytimes.com, Oct. 9):

Turkey’s military incursion into Syria, just days after President Trump announced the withdrawal of American troops from the region, is an unfortunate reminder that United States foreign policy in the Trump era is essentially a mystery to everyone.

That Mr. Trump, after snubbing Turkey’s president at the United Nations, tries to make it all better with Turkey by offering up an American ally, the Kurds, as sacrificial lambs, reminds the world that under this administration, the United States simply cannot be trusted.

This president has now made us complicit in the potential genocide of an ally.

What a terrible burden of guilt he has placed on our military, which was ordered to stand back on the actions against the Kurds, with whom it has stood shoulder to shoulder for years.

The impact of this outrageous decision will be felt by us all for years to come. Pray for the Kurds.
