Some U.S. official is whining because his flock of bastards gets hurt:
"Putin is deliberately targeting our forces," a U.S. official, who is disappointed in the U.S. response to Russia, told Fox News.
"Our guys are fighting for their lives," said the official, estimating up to 150 CIA-trained moderate rebels have been killed by the Russians.
"Our forces", "our guys" - hmm. The official is referring to the CIA-mercenaries who are fighting under al-Qaeda's command:
Advancing alongside the Islamist groups, and sometimes aiding them, have been several of the relatively secular groups, like the Free Syrian Army, which have gained new prominence and status because of their access to the TOWs.
Even in smaller quantities, the missiles played a major role in the insurgent advances that eventually endangered Mr. Assad’s rule. While that would seem like a welcome development for United States policy makers, in practice it presented another quandary, given that the Nusra Front was among the groups benefiting from the enhanced firepower.
It is a tactical alliance that Free Syrian Army commanders describe as an uncomfortable marriage of necessity, because they cannot operate without the consent of the larger and stronger Nusra Front.
The "official" should go to jail for, at least, indirectly arming and supporting the terrorists of Jabhat al-Nusra aka al-Qaeda in Syria.
Under U.S. domestic law Obama justifies his attacks on the Islamic State in Syria (which is illegal under international law) with reference to the Authorization for Use of Military Force Against Terrorists as passed by the United States Congress on September 14, 2001. According to that AUMF:
That the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist ...
If that is the relevant legal code to fight the Islamic State then this even more so applies to Jabhat al-Nusra as it is loyal to the original al-Qaeda organization.
What Russia does, fighting on behalf of the legal government of Syria after having been asked to do so, is not only legal under international law but it is also easily justifiable by the same U.S. domestic law which the U.S. president applies to fight the Islamic State.
That whining official should recognize that a. what "his forces" do is illegal under U.S. law b. what Russia does with "his guys" is legal even under U.S. law and c. that there is always a moral hazard when using such proxy forces.
When the CIA send some idiots to invade Cuba where they were killed or capture it could do nothing and did nothing to protect them because that would have started a much bigger war. This is the same case here. These forces will be destroyed and there is nothing the U.S. can or will do about that. If you are sentimental about the fate of mercenaries and if you do not want this to happen do not use proxy forces but be man enough to go yourself.
