Geopolitical Stabilization 101
Longstanding US policy is to economically ostracize nations we don’t like. Hence the decades-long embargoes of Iran, Cuba, North Korea.
There is no experimental evidence that this works. No nation has changed policy as a result. In fact, the lack of economic ties to these nations means they have nothing to lose economically in a confrontation with America.
Thus, logically, the opposite policy would work better: kill them with carefully chosen kindness.
For example, Iran lacks refining capacity, so they are an oil exporter, but a gasoline importer. An interesting Mideast stabilization policy might be to build refining capacity in Iraq, and encourage gasoline sales into Iran. Increasing Iran’s dependence on a hostile neighbor creates strong incentives on both sides to stabilize both countries.
