But core industries are just head of iceberg, you may not hear, typically 90% of iceberg are deep under water surface, very much like core vs non-core.
Any way, if large entity from core industry goes under, this could lead to killing domino effect for many "underwater" entities.
That is really big problem, which president Trump tried to avoid, when bought share of Intel.
And no, I disagree about battleground for now. What really important, really good strategists know, wars win by economy, not by military, as military could not withstand if they have not enough money for weapons and equipment.
So, basically, now US is stronger than China, so Chinese tops decide to not begin war which will not be profitable, while US is strong.
When and if China will feel competitive to US economically, they will be much more confident to begin war, so now the best what could do US tops to avoid war - to make China weaker and US stronger ECONOMICALLY.
Unfortunately, now China already could make space scale rockets, so competition moved to other space - to computers and semiconductors (and possible branch to nano-industry or bio-nano, or something similar).
If Intel goes under, Taiwan becomes the battleground for WW3.
