The Egyptians were far more aggressive on the tunnels than the Israelis when I was there in Sinai from 2011 to 2012. Not that the Israelis weren’t good, but the Egyptians don’t get a lot of credit for what they do trying to pen the Gaza Palis in.
Israel cannot be as aggressive as Egypt. Their aggression would be perceived as an act of war by the international community. They are basically limited to obvious self defense while Obama is in office.
