There was a slogan on the streets of Seattle: "This is what democracy looks like." You can't love democracy and denigrate protest, because protest is part of democracy. It's a package deal.
Likewise, you can't claim solidarity with Egyptian protesters when they take down a dictator, but act horrified that the resulting government in Egypt, more accountable to Egyptian public opinion, is more engaged in supporting Palestinian rights. It's a package deal.
On Saturday, at long last, the Egyptian government "permanently opened" the Egypt-Gaza passenger crossing at Rafah. A big part of the credit for this long-awaited development belongs to Tahrir. It was the Tahrir uprising that brought about an Egyptian government more accountable to public opinion, and it was inevitable that an Egyptian government more accountable to public opinion would open Rafah, because public opinion in Egypt bitterly opposed Egyptian participation in the blockade on Gaza.
In addition, opening Rafah was a provision of the Fatah-Hamas reconciliation accord brokered by the Egyptian government - an achievement facilitated by the fact that the post-Tahrir Egyptian government was more flexible in the negotiations with Hamas that led to the accord.
Mubarak had a deal with the U.S. government: I obey all your commands on the Israel-Palestine issue, and in exchange, you shut your mouth about human rights and democracy. Tahrir destroyed this bargain, because it forced the U.S. to open its mouth about human rights and democracy in Egypt, regardless of Egypt's stance on Israel-Palestine. When it became clear to Egypt's rulers that subservience to the U.S. on Israel-Palestine would no longer purchase carte blanche on human rights and democracy, there was no reason to slavishly toe the U.S. line on Israel-Palestine anymore.
