Gen. Jack Keane (Ret.) expressed skepticism over Russia's threat to shoot down U.S. aircraft in Syria.
Russia's defense ministry said planes flying in Syria, west of the Euphrates River, would be considered targets after the U.S. Navy shot down a Syrian warplane.
The Syrian SU-22 had just attacked U.S. partner forces battling ISIS and was shot down by a U.S. F-18 Super Hornet.

Keane said on "Fox & Friends" he sees the statement from the Kremlin as more "talk" and "bluster" by Russian President Vladimir Putin.
"That's rubbish. They're not gonna shoot at U.S. airplanes. They're not gonna take on the United States. They have very limited capability in Syria by comparison to U.S. capability," said Keane, a Fox News military analyst.
It's the first time in nearly 20 years that a U.S. fighter jet shot down a warplane in air-to-air combat. The last time was a Serbian jet downed in Kosovo in 1999.
