Is the misalignment of our geopolitical strategies and foreign policies creating armed conflict?

In looking into the failures of foreign policy and armed conflict since WWII I have found a number of cases where disruptions to either strategic interests and foreign policy caused by policy or strategic interests has resulted in some future armed conflict.

One possible example of this is the approach that the Obama administration took in regards to Iran and Hezbollah. The DEA and other intelligence agencies proved that Hezbollah and Iran were engaged in illegal activities in order to fund their terrorists activities. However Obama and his counterterrorism adviser appear to have been lockstep in their own approach to Hezbollah and even more troubling Iran's nuclear ambitions. I fear this subtle misalignment may in turn end up being the source of some armed conflict down the road. Maybe a nuclear arms race within the Middle East or nuclear proliferation via Hezbollah.

Is our foreign policy the cure or the disease in regards to armed conflict?
