“The need for a unified Arab force is growing and becoming more pressing every day,” Egyptian President Abdel Fattah el-Sisi said in a televised speech Sunday.

El-Sisi said Jordan and the United Arab Emirates have offered military help as Egypt amplifies its battle against ISIS in neighboring Libya.

CNN military analyst Maj. Gen. James “Spider” Marks said “it’s about time” an Arab leader like el-Sisi made such a statement.

“Strategically and politically for the region, this is a big deal, and it’s absolutely the right first step,” the retired U.S. Army officer said.

El-Sisi’s statement came after U.S. President Barack Obama called for other countries last week to step up their efforts in the fight against ISIS.
