On a long enough timeline they will eventually convince the US government to build a Gundam. Maybe General Dynamics will do it, doesnt matter. Its the inevitable trajectory we are on. The only reason why they haven't yet is the execs dont know what a Gundam is.
I dunno but Ford, GM, Nissan, and others will help make BattleMechs starting in the 2500s after the first successful combat test in Yakima, WA
