Why a trainer's production location enters the procurement debate

Why not buy the Japanese trainer version mentioned in the discussion?

The reply focuses on where the manufacturing jobs would be, then discusses competing political incentives over jobs and cost.

The follow-up asks why Britain would not simply buy the Japanese version mentioned earlier. The answer points to the location of manufacturing jobs. Alex then offers his interpretation of British party behavior: governments emphasize domestic employment or national production when under electoral pressure, and cost savings when more secure. Labour and Conservative examples are both discussed. This is his experience-based account of political incentives, rather than a universal rule about procurement decisions.
