Iran, North Korea and Russian Federation are indulging in bellicose barking, but at least Obama is no longer empowered to make things worse. The United States' top diplomat is in Moscow meeting with top officials there including President Vladimir Putin.
As US secretary of state Rex Tillerson held extended meetings with both Russian foreign minister Sergei Lavrov and the country's president Vladimir Putin in Moscow, Mr Lavrov accused the US government of undertaking an "illegal attack against Syria" and criticised Washington's "confusing and sometimes openly contradictory ideas on the entire range of bilateral and worldwide issues".
It was no accident Putin made Tillerson wait.
The US secretary of state says there is a "low level of trust" between Washington and Moscow and they "cannot have this kind of relationship". Washington warned Moscow, and Russian troops at the base were not hit.
The U.S. and Russian Federation may not quite be engaged in a new Cold War.
But the USA said Moscow's continual backing for the Syrian government would only make it more isolated.
He also rejected American claims of certain evidence that Assad ordered the chemical attack.
Russia's veto of a United Nations resolution condemning a deadly chemical attack in Syria and pushing Bashar Assad's regime to co-operate with an global inquiry put the country on the "wrong side" of the argument, the Foreign Secretary said. But Tillerson repeated the administration's new belief that "the reign of the Assad family is coming to an end".
Still, Tillerson sought to stress the positives from his meetings.
"One could say that the level of trust on a working level, especially on the military level, has not improved but has rather deteriorated", Putin said in an interview broadcast on Russian television. -Russian ties and identify problems.
Russian Federation presented a separate draft text condemning the USA military strikes in Syria and requesting an OPCW investigation, but it was uncleaer whether that measure would come up for a vote.
But such hopes appeared optimistic as the diplomats outlined their sharply diverging views on Syria.
The Wall Street Journal cited Trump as saying that Assad's use of chemical weapons again would elicit another military response, but he also said he would not intervene in depth in the conflict. And he suggested that possible war crimes charges could be levied against the Syrian leader.

And House Democrats held a conference call earlier this week to discuss their own strategy on a war authorization, in which Congress would vote to give Trump the authority to conduct military action but potentially limit the steps he could take, such as deploying ground combat troops.
Russian Federation on Wednesday rejected calls to withdraw support from Syrian president Bashar al-Assad, claiming that would curtail efforts to fight Islamic State in the country and querying U.S. claims that the Syrian leader was behind recent chemical attacks.
She told the U.N. Security Council on Wednesday: "We are not going to look the other way".
Mr Trump also backtracked on his criticism of North Atlantic Treaty Organisation at a joint press conference with its secretary general Jens Stoltenberg, saying: "I said it was obsolete; it's no longer obsolete".
