An outright example of FOX News lying to manipulate the outcome, during the first 2015 Republican debate:
BRET BAIER (Fox News channel anchor):

Dr. Carson, in August of 2012 President Obama famously declared Syrian President Bashar al-Assad used chemical weapons, quote, “that’s a red line for us,” and that there would be enormous consequences.

One year later, and with overwhelming evidence the Assad had, in fact, used chemical weapons and crossed that red line, President Obama declined to use military force against the Assad regime.

As president, would you have used military force there? (source)

THE TRUTH:

(video) Leaked Documents: U.S. Framed Syria in Chemical Weapons Attack

(video) U.S. Intelligence: Rebels Used Sarin — And is there a moral imperative to bomb Syria even if there were 400 children killed? How about 500,000 killed by US foreign policy that Albright said was worth it?

[Why-they-hate-US video] Webster Tarpley: Syria & Iran, the Colorado Shooting — We are murdering Syrians, falsely blaming it on Assad in order to justify invasion so Syria can’t strike us when we/Israel strike Iran. The German people are being told while our presstitutes go along with the deception.

Skousen: US and Israeli Involvement with ISIS — The UN has now published a report that claims that Israeli Defense forces have regular contact with ISIS — The main motive behind the US funding of and creation of ISIS is to take down Assad. Israel is refusing to bomb Iran until Syria is eliminated as a retaliation threat

(video) Skousen: US covertly funding overthrow of Syria so Israel can attack Iran without Syrian opposition

Joel Skousen’s brilliant analysis! Syria: West Using Terror to Provoke Defections — The Syrian overthrow is a “must accomplish” goal of the US and Israel prior to the coming attack on Iran … so that Israel doesn’t have to face Syrian missiles as part of the inevitable Iranian retaliation.
