Israel should exist... you may never now it might one day become a musllim country if allah wills. If you dont believe me, go look at ta'if and makkah and medina and Iraq and all those countries they used to be kuffar countries and now they are great muslim countries.
Ta'if for example whne they prophet (saws) visted there to preach they rejected him and threw rocks at him and the angel asked if he could destory them .... but he said no and made dua' to guide them. Now look at them, its a muslim country. I posted this too , the guy who went to india to preach was from Ta'if ... so the pakistani's and indians would have been kuffaar if the prophet (saws) would have destroyed ta'if.
May allah guide the israelis to the dareeqel Mustaqeem. Ameen.
