Well after Barack Obama came into power, this cable from August 2008 proves that Washington had every intention of helping its close friends; the dictatorship of Egypt and occupying Israel:

Since the Egyptian-brokered “tahdiya” (“calming”) between Israel and Palestinian groups in Gaza took effect June 19, rocket attacks from Gaza have decreased, and Israeli public pressure on the GOE to stop smuggling via tunnels into Gaza has relaxed. However, smuggling remains an important security issue. We are working closely with Egypt to develop a comprehensive counter-smuggling strategy. Assisting the GOE with deployment of a U.S.-supplied counter-tunneling system on the Egypt-Gaza border provides Egypt with an opportunity to more fully exploit tunnels and break up smuggling rings. As Egypt moves forward into a new phase of counter-smuggling efforts, we will continue our cooperation in a variety of areas: helping interdict smuggling on Egypt’s western, southern, and eastern borders; economic development in the Sinai; border security assistance; and de-mining. End summary.
