The president made his latest statement in a tweet Thursday morning.
Trump posted a tweet on Wednesday warning Russian Federation to "get ready" because missiles "will be coming" to Syria.
Chancellor Angela Merkel said after speaking with Macron on Thursday that Germany won't participate in possible military action in Syria, but supports sending a message that the use of chemical weapons is unacceptable. Trump notably did not rule out plans to attack Syria in retaliation for the weekend's suspected chemical attack on civilians at the hands of the Assad regime.
Half a world away in New York, Russia's United Nations ambassador warned the priority in Syria was to avert US-led strikes that could lead to a unsafe confrontation between the world's two preeminent nuclear powers.
"Russia vows to shoot down any and all missiles fired at Syria", Trump wrote.
"Get ready, Russia, because they will be coming, nice and new and "smart". We are continuing to assess intelligence and are engaged in conversations with our partners and allies". "We're still working on this". This is in contrast to an incident one year ago in which the USA government had video and other evidence of certain aspects of an actual attack by Syrian aircraft, which involved the use of sarin gas.
That assault prompted the U.S. to launch several dozen Tomahawk cruise missiles at a Syrian air base.
Britain's government weighed the possibility of military action against Syria on Thursday but faced growing scepticism from opposition leaders and deeper divisions in a country still haunted by its role in the US-led invasion of Iraq.
"We don't comment on submarine movements", a spokesman said. We are totally predictable.
Syria and Russia have denied using poisonous gas in Douma on April 7, with Russian Foreign Minister Sergei Lavrov saying that Moscow had "irrefutable" evidence that the attack in Douma was a "staged event". And he insisted it remains US policy not to be involved directly in Syria's civil war.
"Parliament must be consulted on this", he said.
Shortly after his tweeted warning to Russia, Trump took a more conciliatory tone in lamenting that the U.S. -Russia relationship "is worse now than it has ever been". "So we're looking at that very strongly and very seriously".
The President will meet with his national security team at the White House on Thursday for further discussions on the USA response.
Trump's administration has sought to show toughness on Russian Federation, with a series of economic and diplomatic actions, including new sanctions last week against government officials and oligarchs.
The U.S., France and Britain have been in extensive consultations about launching a military strike as early as the end of this week, U.S. officials have said.
