Sorry, Don't support it. I'm assuming you're referencing the oil pipeline deal with the Saudis.
You want to fight terrorism and claim its an a major issue. Well maybe stop fukking up other countries in order to get cheaper oil. You can't have both.
Secondly, this idea that some geopolitical dominance needs to be asserted is usually in the interest of a few corporation than in the average person's interest. The UK seems to have survived having its empire deconstructed. Are they as geopolitically important or as wealthy? No. But the average citizen isn't destitute either and its still a first world country.
While your government is pouring billions, if not trillions, into these games, your domestic life gets progressively worse. Your wages don't rise, your schools get worse, your healthcare gets worse, your infrastructure gets worse. Stuff most people actually care about more on a day to day basis. Maybe if you weren't pouring trillions of dollars into these games, you can pour it into those things instead. Funny enough, these are things the UK instead of maintaining a world wide empire spends money on instead.
But folks keep falling for getting fukked over in the interest of the few because it tickles their homelandesque geopolitical chess fetish.
