The intelligence agencies do have some really smart people burdened by the constant inter-agency fighting and the dummies at the top and politicians who not placed some of those dummies but can't keep sticky fingers out. The top people also spend a lot of effort fighting for more money-power. The fact that the government has totally incoherent strategy for dealing foreigners and local threat also making it totally hit and miss as whether the agencies have any success. True they totally fail to use the international understanding of foreign countries/people by civilians well. They actually don't need to be very smart- coherent cooperation would be more effective.
