There are way too many coincidences all pointing in the same direction. Combine that with the Chinese culture of cutting corners at virtually every opportunity to get ahead and you end up with an unintentional lab leak as the most likely source.
China needs to pay a very heavy cost for this. Their cheating and cutting corners has caused incalculable world wide damage this time around. They've had numerous rounds before but this one is at an entirely new level. Enough is enough.
Essentially, since we aren't in a shooting war, here, I think the repercussions could be a win-win for the US.
Primarily in trade and manufacturing.
We should rebuild our own manufacturing base, raw materials (ore) to finished product. From Rare Earths to base and precious metals, pharmaceuticals, steel stock to electronics, and especially with more things becoming interlaced and subject to remote access (5G), we should make our own and not trust a likely future adversary with controlling the manufacture of our specific technology nor access to that.
In the event of a shooting war, are we going to procure our materiel from a potential adversary? That which is necessary to the war effort from the front to at home?
Sending manufacturing offshore (building plants there) only sent capabilities and techniques with it that ultimately have dual use--after all, everyone during WWII here adapted.
(Singer sewing machine and Remington typewriter were making firearms. Auto manufacturers made tanks and heavy trucks, etc. ) But we had the iron ore and steel industry to back that up. The components for the radios were made here.
Even today, pillow manufacturers shifted to making masks.
This is a wake-up call.
Border security: Yes, sounds like a fine idea. Make it so. It will never be 100%, but that is no reason not to strive for 99.999%
National Security: Currently, virtually any foreign power can send students to the US to loot whatever information, research, and current knowledge and send it home. Similarly, the loss of intellectual property to other powers' likely state sponsored robbery must be horrendous. It's time to reconsider how beholden our University system (especially STEM) is beholden to and infiltrated with foreign powers.
And it is time to get those in our government to start putting America First again.
