It has been accompanied by a large spike in military spending globally. The backlog of foreign military sales of US weapons just waiting for approval is ~$1T.
Every USA president since the fall of the Berlin Wall has implored NATO members take control of their own defense. The US has long since abandoned the two theater war doctrine. The US is not going to fight Russia. Doing so would just be taking the bait to split their forces when China simultaneously decides to mobilize in the South China Sea. All of USA military planning has been in preparation for that theater.
Trump's belligerence has accomplished the US policy goals of every administration for the last 40 years.
Do you have more information about this, or a source?
I can say with a reasonable amount of confidence that going "but china" isn't going to help the US much going forward.
spoiler alert: the cozy days of the colonial west are over. it will all be over soon, and one can hope but i don't guarantee surviving will be necessarily a lucky draw.
btw, this would explain fermi's paradox pretty well.
Unfortunately I think the actual reason is because they know (despite what they say in public) that climate change is a real and present danger, and the resource and migration wars are coming.
I also feel like the boomers offshoring everything to China in the 70's is one of the reasons things are worse off nowadays, but I digress.
This started to unravel as things got more tense with the increasing militarization of China and centealzatuon of power in Xi as well as well as Putins more aggressive moves.
The Ukraine war kicked the whole structure over and dillusioned a lot of people. The problem is that if suddenly history isn't over and war is a possibility again you need to start preparing for it. If you choose not to play the great game you don't avoid it, you just get crushed, and so as a matter of national survival and security you need to start preparing to meet near peer adversaries, but they see you preparing and they up their defensive preperations and military spending because you did and if they don't they might be crushed, and you see this and have to up your spending, and suddenly a massive amount of wealth is going to preparing for conflict.
The whole situation is almost identical to how things were on the eve of the 20th century, with radical advances in technology overturning decades of military theory and strategy, everyone is tense with alliances constantly shifting and real politick dominating everything because the alternative is the fate of the Belgians who had their country shorn from them and their people massacred by Imperial German forces. At the same time we see growing social unrest within nations (stoked by foreign actors trying to disrupt social cohesion of their potential enemies) and everyone posturing with more and more bluster because to be precieved as weak is to invite death as no one wants to make friends with a weak link.
The one important lesson to be taken however is that WW1 didn't have to happen the Great War could've been prevented, a major part of the conflict was the certainty that there was going to be a war. If we can choose to instead try and be peacemakers and bring the overall temprature of discourse down we can avoid another human catastrophe.
And maybe introduce some technological improvements, too. Like portable millsites and leach pads so you don't fuck up the landscape with dead buildings and environmental waste. And maybe look into some chemical process improvements, like using DMSO instead of cyanide for leaching gold.
Oh, and look into using Z-pinching for mining so we don't need explosives, we just need capacitors and metal tubes and drills to make precision tunnels to grab ore and leave more of the land intact.
Are they cheaper? They are open-weight, so in theory, they are cheaper to run and do with them as you wish.
The problem is that they come from a place with a long and storied history of attacking digital assets in the US and the West in general.
