Russia was not forewarned about the strike, however, the American military used the normal channels to avoid escalation.
The US defence Secretary Jim Mattis stated that the target for attack was chosen with the expectation to deprive the regime of Bashar al-Assad’s ability to use chemical weapons and to minimize losses among the civilian population of Syria. Hence, the choice of targets.
Mattis expressed confidence that the Syrian authorities are responsible for the use of chemical weapons in the Duma. According to Mattis, the attacks were made at the research center, where he conducted the development of chemical weapons, and chemical weapons storage.
General Joseph denford, Chairman of the joint chiefs of staff , said that he had no information about casualties among American troops. He stressed that the first wave of attacks completed. In it participated, including combat aircraft pilots.
However, the Pentagon has made it clear that the military campaign will continue and will end only when the regime of Bashar al-Assad will refuse the idea to use chemical weapons.
According to Denford, it has no information about the reaction of the Syrian air defense systems.
Denford also said that Russia was not forewarned about the strike, however, the American military used the normal channels to avoid escalation. Denford said that the attack was done to minimize the chances of losses among the Russian servicemen.
According to Jim Mattis, the Assad regime did not heed the warning – last year’s attack on a military airfield – this time, the U.S. used twice as much military capacity.
