I tend to agree.
The problem, repeatedly, is that small localized wars become weapons dumps for both sides; escalating the conflict and dramatically increasing the bloodshed where action in one place leads to horrific consequences in another. Over and over and over again.
One example: The US pours weapons into Israel, the Communists pour weapons into Muslim countries who have become addicted to Amin al-Husayni's brand of Nazi fueled hatred of the Jews. A man so toxic even the king of Jordan banished him. The Arab-Israeli wars become a weapons and training hot bed, and serves as an operational laboratory resulting in the concept of the AirLand Battle Space. When an area serves as a laboratory for both sides to test how effective their current weapons are against the adversary's, peace is usually temporary.
Another: The Khmer Rouge dramatically expands their power base over time, transforming from angry Cambodian college students in Paris headed for the barricades into the overlords of The Killing Fields. The common consensus is the great leap forward in their ability to seize total power came because of outrage at US carpet bombing, Operation Menu. Coppola doesn't hide Col. Kurtz in a Cambodian temple by accident, and even he is tame compared to the bloodlust exhibited by 'Brother Number 1', Pol Pot.
Yet another: Out of the rubble of Soviet occupied Afghanistan rises a small sect of heavily financed, highly dissatisfied, religious fanatics who can't decide if they hate the Soviets more for occupying them, or the Americans for pretending to care while weaponizing them and then abandoning them to their ancestral poverty when they are done with them. This simple act designed to drain the Bear's strength and retard his ability to act in Europe ends up plunging America into decades of involvement in a Land War in Asia ('one of the classic blunders'). Last I checked, they're still around.
This is not a tithe of the tale, but illustrates the point.
