The results of the revolution in Egypt aren’t clear yet, but they’re already remaking global politics. Egypt announced that it will open the Rafah border crossing into the Gaza Strip, the Palestinian territory controlled by Hamas, this weekend. That will allow goods to enter the strip, which has been blockaded. Israel and others worry that will create a lifeline of supplies and arms for Hamas, a terrorist group, but Egypt says the crossing will be monitored by European observers and Israel, to screen out weapons and militants. The crossing was briefly opened in 2007 after Palestinians overran it, and Hamas has used tunnels to smuggle goods in and out.
