Isis says they did it.
Russians scoff at that claim.
FOX says it just crashed due to a systems failure of some sort.
Obama regime was talking about combat troops not being really combat troops.
Now the big question is, which liar is lying?
Well, with the Obama regime in the mix, which two.
Until the crash investigators can piece together the evidence no one can know what caused the aircraft to crash. Even if you wanted to speculate that ISIS knew they had placed a bomb aboard the aircraft, they would have no way of knowing whether the bomb or a technical fault caused the crash before the bomb could detonate. All of the reports about the cause of the crash we are currently seeing amount to nothing more than speculation, with some of the speculation being totally uninformed and some of the speculation being fairly well informed. A surface-to-air missile (SAM) leaves some quite obvious shrapnel evidence, so the absence of such shrapnel evidence usually will rule out the crash being caused by a SAM or an air-to-air intercept missile (AIM) fired from a fighter aircraft.
Likewise a large internal explosion due to an onboard bomb will typically cause the fuselage to rupture in an outwards direction and leave residues from the explosive all over the objects where the explosive was placed.
So, it does no good to falsely accuse these sources of giving false conclusions for the cause of the crash, when in fact no one is doing anything more than speculating on the incomplete evidence seen so far.
