I would bet it does not mean that as, unless I'm mistaken, these people were in the US to install and work with proprietary, new technology.
can't just chuck randos at that.
Also, seems like Korea (And other Asian countries) are cooling FAST to investing in the US. Expect to see what we saw with Trump 1.0 (a lot of promise and ALMOST no follow through).
You
can chuck randos at it
once. Just like any vehicle can be used as a minesweeper
once. It's not as if lithium-ion batteries aren't notoriously tetchy if they aren't treated with respect.
Just like overseas investments - the odds of being able to even find 300+ more South Korean engineers who would be willing to travel to the US, let alone those with experience of proprietary equipment.
Then there's all the other RoK firms looking at their plants (both live and under construction), plus almost all of the civilian shipbuilders in the US
who are no doubt thinking "if it could happen to them, what's to stop it happening to us?"
Lastly there's the impact of having the RoK government launching a human rights probe over the treatment of their citizens by ICE during the raid, and their subsequent week in detention. As it stands any Korean company or politician that suggests investing more than a pint pot of warm spit in the US is looking at a find-a-new-line-of-work level domestic backlash.
And that would include the $350bn of investment that they were effectively blackmailed into promising in the (as yet not signed) art-of-the-deal.
