The U.S. believes that spying on the whole world somehow gives them early warnings, and they managed to completely miss the Korean War, the German Wall, the Cuba Crisis, the reconquest of South Vietnam by the Vietcong, the end of the Somoza Regime in Nicaragua, the polish Solidarnosc, the fall of the Berlin Wall, the subsequent dissolution first of nearly all communist regimes and then the Soviet Union, the conquest of Kuwait by Iraq, 9/11, Somalia, the Arabian Spring, the turning of the Arabian Spring into a strengthening of the extreme wahhabitian Islam, the ISIL conquest of North West Iraq, the annection of Crimea, and the pro-russian uprising in the eastern Ukraine.
But they were pretty sure they find Weapons of Mass Destruction in post Gulf War Iraq.
Somehow the whole spying does not yield the expected results. I wonder if still more spying and mass surveillance will solve this. And more IT infrastructure to dig through the data. And still more money to pay more analysts. And do everything to weaken any attempt to make communication secure.
