The Trump administration said last week it was removing NATO ally Turkey from the F-35 fighter jet program, a move long threatened and expected after Ankara began accepting delivery of Russia’s S-400 air defense system.
Under a 2017 U.S. sanctions law known as CAATSA, Trump should also impose sanctions on Turkey for doing business with the Russian military, although he has not yet said whether will do so. CAATSA does not set a timeline for sanctions.
Lawmakers from both parties have said they want to see a robust response, but Trump’s fellow Republicans have expressed greater caution.
Aides said they did not expect any legislative action before September 9, when lawmakers return from their summer recess.
Trump brought some 40 Republican senators to the White House to discuss the issue on Tuesday. Jim Risch, the Republican chairman of the Senate Foreign Relations Committee, said there was a “spirited discussion” but no conclusion was reached.
“I’ve said for a long, long time that it’s unacceptable for Turkey to have the S-400. And that’s the point I’m at. Now, what does that translate into? Let’s move forward and see how that goes,” he told reporters.
The F-35 stealth fighter jet, the most advanced aircraft in the U.S. arsenal, is used by NATO and other U.S. allies. Washington is concerned that deploying the S-400 with the F-35 would allow Russia to gain too much inside information about the aircraft’s systems.
Some lawmakers said it was essential not to sour relations with Turkey, an important player in dealings with neighbors Syria and Iraq. Turkey has threatened to retaliate if Washington imposes sanctions over the S-400.
“Turkey is and continues to be a very important country, a very important NATO ally. We have lots of things that we do with them. So you want to send the message but you don’t want to alienate them forever,” Representative Mac Thornberry, the top Republican on the House of Representatives Armed Services Committee, told reporters.
Democrats said Trump should respect CAATSA, which he signed into law reluctantly after it passed both the Senate and House by veto-proof majorities two years ago.
“The law is unequivocal,” Senator Bob Menendez, the top Foreign Relations Committee Democrat, told Reuters.
Senator Jeanne Shaheen, a Democratic member of both the Foreign Relations and Armed Services panels, said it was important to impress on other countries that CAATSA has teeth.
“The administration needs to show strength and not set a disturbing precedent through inaction on CAATSA,” she said in a statement to Reuters.
