I was reading this morning that when Ramzi Yousef (the originator of the chemical/bomb plot in '95), was arrested, they found "dolls" with concealed chemicals in his digs.
After the staging of dead children in Qana, it's conceivable that the most horrendously inhuman plot is not beyond these people. The pregnant woman could be used to fake labor in the terminal, or in mid-air, as a distraction, and the infant's toy, pacifier or diaper could contain a chemical component.
If you place no value on human life, anything goes.
And when we as a nation realize what these people are capable of, only then can we win the war against them.
