Dear Editor: For the first time in U.S. history foreign nations will protect the skies over the U.S.A. during this war we are engaged in. From my morning paper, I quote, “NATO forces will cross the Atlantic to defend the United States. Five AWACS surveillance planes and their European crews will circle American skies to free up U.S. Air Force AWACS for missions elsewhere on the globe.” This sets a dangerous precedence. I called our two Texas Senators and others in Congress. They are aware of this and it’s okay with them. The only way to stop this abuse of power is to withdraw the U.S. from the United Nations’eventually. AGNES H. HICKS Wimberley, Tex.
