I agree to a point. US is "hooked" to war as it feeds the profits and the subsidies of the military industrial complex. Especially in the eastern mediterranean area and middle east US escapades have been hugely destabilizing.
However, given the current world stage in total with such jolly players with extraterritorial ambitions as Russia and China, I would much prefer that US was ready to aggressively project force than not. As a counterbalance.
Especially as I live in Finland, I much prefer having US backed Nato force as a counterbalance to which ever clique in Kremlin has control of the Russian military antics.
This is anything but clear cut.
