I merely pointed out that Egypt's claim was unconfirmed and hotly denied by Hamas, while (and this is the bit you chose not to see) the Muslim brotherhood asserted quite strongly that Israel WAS responsible.
Don, you refer to a different thread.

Egypt's ruling Muslim Brotherhood hate Israel (Jews?) and blame them for all evil.
When the incursion happened, blaming Israel was a knee jerk reaction.

However, power brings responsibility.
They clearly knew who was really responsible, and had to take action to stop it happening again.
They closed and flooded all the tunnels from Gaza, and took no action nor made any more statements against Israel.
