Al Qaida has explicitly threatened Poland with Madrid-like terrorist attacks, Polish security officials said this week. A document in Arabic posted on an al Qaida Web site calls for jihad against Poland, helpfully identified as a country in Central Europe on the coast of the Baltic Sea. The document, written in the flowery style associated with the terrorist group, notes that Poland is a member of NATO with a strongly pro-American leader, President Alexander Kwasniewski. We ask Allah: Let the earth swallow him! it says of Kwasniewski. Poland has 2,500 troops stationed in Iraq.
