Not taking side on this forum. But two points of interest I would like to mention.
1 Although Hamas has fired lots of rockets into Israel so far they have killed few people. This could perhaps easily change if these rockets where armed with a biological payload.
2 There was a "report" that ship loaded with arms was intercepted headed for Gaza on board was "reported" to be among other things artillery shells. Now as far as I know Hamas has no artillery. But as I understand it these are the basics of Improvised Explosive Devices, very handy for stopping any tank.
Now there is a story all Jews would know well, it is about David and Goliath....You know the rest.
