Without additional troops to ensure victory in Iraq, the U.S. could find
itself more vulnerable to terrorist attacks at home, Sen. John McCain said
Sunday.

HOWEVER -

Gen. John Abizaid, the top U.S. commander for the Middle East, told the
Senate Armed Services Committee last week he believes troop levels should
remain steady for now. He said it was possible to add 20,000 troops for a
short time, but it would be unrealistic to raise troop levels as proposed by
McCain and Sen. Lindsey Graham, R-S.C.
Abizaid said the American military in Iraq is stretched too thin already,
and sending over a bigger, more permanent presence would undercut efforts to
force Iraqis to take on more responsibility.
