21st Century Wire says While you were watching the presidential reality show, the Pentagon was busy putting boots back on the ground in Iraq and threatening to invade Syria.Watch a video of this report here: CNN reports that the unit has been  setting up safe houses, establishing informant networks and coordinating operations with Iraqi and Peshmerga units  in the past few weeks.Defence Secretary Ash Carter said: The only thing I ll say is the Expeditionary Targeting Force (Delta) is in position, it is having an effect and operating, and I expect it to be a very effective part of our acceleration campaign, Carter explained that the deployment of special forces was to make ISIS  fear that anywhere, anytime, it may be struck. Delta Force is 200-men strong in Iraq, and will be carrying out raids on targets, recovering hostages, eliminating terrorist commanders and gathering intelligence from enemy locations.Carter also said: This force will also be in a position to conduct unilateral operations in Syria. What Carter is really saying is that Delta Force may be used illegally in Syria, as they have no mandate from the sovereign Syrian government, or the UN for that matter, to conduct any operations at all on Syrian territory.Some might even say this is an American threat to invade Syria.Russian actions, on the other hand, are absolutely legal under international law, as they are fully sanctioned by the Syrian government.Earlier this week we learned that the Russian special forces unit Spetznaz was infiltrating ISIS with undercover operatives, which enabled airstrikes to hit within just three meters of their targets.Do you think Delta Force will have a real effect on the fight against ISIS?GET THE FULL STORY ON THE SYRIAN CRISIS: 21st Century Wire Syria Files
