It is not clear that cutting off aid will indeed save lives especially if it is replaced by Saudi Arabia. Beyond that there are contentions that thousands of lives have been saved as a result of Egypt's strong military.
In difficult times it is best to fall back on core principles. We preach democracy. Demand control be released back to the Muslim Brotherhood, educate our country on the Muslim religion so the populous understands whether it is compatible with "Freedom For All" and require half the aid be used for humanitarian reasons by giving it to the legitimate government instead of the military. The aid should be in the form of food and services.
