They reached an agreement with the government but not with people....
This is why this "agreement" is doomed. Now Tsipras has the enemy outside of greece, and inside of greece because their own voters and not only that, part of his own party its against him now.
Its hard to believe people in just about any country could be for their leaders. The leaders of the world collectively are acting for their own gain, and for the benefit and preservation of the power the elites hold (bankers, billionaires, military leaders, etc).
The people need to realize this and stop accepting the debt slavery being cast upon them.
