I agree with many. The Military Industrial Complex of the US Government is a power hungry, war generating enterprise that will suck Thailand dry on the cost of spare parts for their jets.
Likewise I agree with the Thai officials... there are a much better use for this money in Thailand, for both infrastructure and building innovation capacity (R&D) among its people. Develop new industries, and build strong linkages across the Asian frontier.
War machines (fighter jets) are for war mongers! Not peace-loving people.
