There are two signs of a possible U.S. entry into Syria. One is that the U.S.S. Eisenhower is offshore along with other U.S. warships. The other sign is an unconfirmed report from PressTV, which is an Iranian source, that 3,000 U.S. soldiers have returned to a base in Iraq secretly. There are also leaks coming out of Europe that a NATO invasion, along Libyan lines, is imminent.
