It's definitely not a pretend.
If I have to sum up US actions recently then goal is very clear:
Trump is trying to reposition the US from being the global economic enabler which costed them alot to being a strategically self-reliant superpower, even if it means breaking existing world order.
US is trying to become a self - reliant economic fortress which engages with the World at it's own self - reliant terms.
In short term, this path would definitely lead to chaos and hardship. People will struggle and resistance would mount from both within and outside the US.
But, tbh, the fundamentals of US economy are strong enough to overcome this.
It's the transition where real catch lies and where I feel Trump hard hand approach could become a massive problem.
He's forcing it down like kind of shock therapy instead of gradual transition and we all know what happens with such approach especially when he's not enjoying public support at that scale....big firms can't be coerced and pressuring them could lead to relocation, allies would be alienated with hardly any room for error.
His path is high risks, high gains
And, considering how he doesn't enjoy that much public support - I really feel he should tone down his approach - not path but approach to accomodate concerns
