WASHINGTON -- As Russia and Syria again warned President Trump against taking military action against Bashar Assad's military over a suspected chemical attack, Mr. Trump said a strike could be coming soon, "or not soon at all!" His Thursday morning tweet came after a day after Mr. Trump appeared to get ahead of his own military and intelligence teams by stating publicly, again on Twitter, that the U.S. military was.
President Trump said earlier this week that a decision on the U.S. response
The president also appeared to chide an undefined national or international audience in his tweet for not thanking the United States for its, "great job of ridding the region of ISIS."
"Never said when an attack on Syria would take place. Could be very soon or not so soon at all! In any event, the United States, under my Administration, has done a great job of ridding the region of ISIS," Mr. Trump tweeted early Thursday. "Where is our 'Thank you America?'"
Mr. Trump's tweets the previous day, warning Russia to "get ready" for an attack with "nice and new and 'smart!'" weapons in response to the suspected chemical attack on the Damascus suburb of Douma came as U.S. authorities continue working with international partners to verify that a chemical attack occurred, and if so, with what.
French President Emmanuel Macron, a key ally in the U.S.-led coalition in Syria, said Thursday, however, that the evidence was clear enough.
"We have the proof that last week, ten days ago, chemical weapons, at least chlorine, were used and they were used by Bashar al-Assad's regime," Macron told French network TF1.
White House press secretary Sarah Sanders said Wednesday that Mr. Trump was considering "a number" of options that potentially included missile strikes. "All of those options are still on the table," Sanders said. "Final decisions haven't been made yet on that front," she said, and no timeline for any strikes had been established.
Syria's Assad clearly thinks a strike is imminent, however. While continuing to cast warnings against military action, he was also taking steps to prepare for it.
The Syrians have begun dispersing their aircraft to make them harder to hit, including sending some to airfields where Russian aircraft are based, betting that the U.S. will not strike there, CBS News senior national security correspondent David Martin reported Thursday.
Russia's government, appearing keen to ease the escalating tension, said early Thursday that communications continue with U.S. officials on a "de-confliction" phone line established to avoid unintended clashes in Syria. There were no plans, however, for President Vladimir Putin to talk directly with Mr. Trump.
Defense Secretary James Mattis is scheduled to testify before Congress on Thursday morning, but Martin reports the military chief is unlikely to reveal anything about Pentagon plans for a strike against Syria. That conversation will take place behind closed doors at a meeting of the National Security Council on Thursday afternoon.
Former Vice Chairman of the Joint Chiefs of Staff Sandy Winnefeld, now a CBS News analyst, expects any U.S. missiles aimed at Syria to come from a number of different directions.
"It's likely that we'll use a combination of platforms including aircraft, surface ships and submarines," Winnefeld said. "The Russians probably will not know where the submarines are or that they're there."
The head of the Russian military, General Valery Gerasimov, has warned that if Russian officers in Syria are threatened by American missiles, they will shoot them down.
Russia has positioned a state-of-the-art air defense system in Syria, but Winnefeld says that shouldn't prevent U.S. missiles from reaching their target.
"These weapons are designed to survive all of the way to their target," he said. "So it will be difficult for them (Russia). They may hit a couple of them, but in general, these weapons tend to get where they're headed."
Winnefeld said the best way for a Russian officer to avoid being hit, is to stay away from Syrian military installations.
"I think it's very unlikely that we would directly and intentionally target any Russian forces that are in Syria, so the way that a Russian officer or person would be harmed is by participating directly in Syrian military activity."
Assad, along with his Russian backers, warned again on Thursday that the threat of military action from the U.S., "and any possible actions, will only contribute to further destabilization in the region."
Russia and Syria have said there is no evidence that the alleged gas attack on Douma even took place, but at the White House, Sanders said, "the intelligence provided certainly paints a different picture, and the President holds Syria and Russia responsible for this chemical weapons attack."
Public reports do strongly suggest chemical weapons were used by Syrian government forces, which currently surround Douma. In a joint statement, the Syrian Civil Defense (White Helmets) and Syrian American Medical Society have said victims of the attack exhibited, "symptoms indicative of exposure to a chemical agent."
