WASHINGTON (JTA) — President Obama asked Congress to delay a vote on whether to strike Syria while he consults with Russia over a deal that would end Syria’s chemical weapons program.

“I have therefore asked the leaders of Congress to postpone a vote to authorize the use of force while we pursue this diplomatic path,” Obama said in a national address Wednesday night.

The Russian option, which emerged over the last two days, would transfer Syrian chemical weapons to international control for destruction. Syrian officials have said they will consider it.

A number of pro-Israel groups have in recent days heeded the White House call to urge Congress to endorse a strike, although it seemed an uphill battle, considering the lack of popular support for such a strike and resistance among a majority of lawmakers in the U.S. House of Representatives.

These groups and the White House have emphasized the Israel is not the preeminent factor in considering such a strike, and although Obama cited in his speech a threat to U.S. allies, including Israel, should Syrian’s Assad regime become more promiscuous in the use of chemical weapons, he also said that Israel should not fear retaliation in case of a U.S. strike.

“Neither Assad nor his allies have any interest in escalation that would lead to his demise, and our ally, Israel, can defend itself with overwhelming force, as well as the unshakable support of the United States of America,” he said.

In making the moral case for a strike should such a deal fall through, Obama cited the horrors of the 20th century, including the Holocaust, noting that these were premises for international bans on the use of chemical weapons.

“In World War I, American GIs were among the many thousands killed by deadly gas in the trenches of Europe,” he said. “In World War II, the Nazis used gas to inflict the horror of the Holocaust.”

Sen. John McCain (R-Ariz.), a foreign policy leader among Republicans, criticized Obama’s plan to entertain the Russian offer for lacking particulars, but did not dismiss it out of hand.

“Such a plan would require the United States, together with our friends and allies, to immediately introduce a tough U.N. Security Council Resolution that lays out what steps Syria would have to take to give up its chemical weapons, including making a full and accurate declaration of all of its chemical weapons and granting international monitors unfettered access to all sites in Syria that possess these weapons,” McCain said.
