Let's say you start counting at the moment the kidnapping happened - you should have bombed Gaza by now. If you ment "starting" when you said it, let's say 7pm sunday by Israeli time - Tanks should have entered Gaza.
Ok - maybe I'm the stupid here, let's say you ment 24 hours ultimatum from midnight Israeli time... so tanks should enter now? How about after your ultimatum was answered by 3 rockets? How about when Hamas leaders can't stop rolling on the floor with laughter? How about now? Can you hear now? Maybe its the cell phone company?
