re: How does Hamas amass weapons to coordinate such a strike if they are blockaded?

We can't stop drugs or people from coming across our southern border(well we could if we put forth the effort). So how do you think Israel and others could actually stop smuggling of arms and simple rocket launchers and such? There are tunnels, trucks, ships, aircraft moving in and out of that area of the world.

The scum will figure out a way to get their guns in.
