To be frank, what I'm more worried about (well this and also our families friends and their family that reside in China) currently actually more than a global conflict (well as long as that conflict doesn't directly effect me tbh its kinda like the other side of the world). is well...its very likely the far right and the crazies may try attempt #2 at overthrowing the government. I mean they could easily take advantage of a huge war if the US is in middle of one.
Last year's incident required what amounted to a perfect storm of contributing factors that will no longer be in play. Most significantly, response forces were either actively crippled, or else people were afraid to send forces in out of concerns that Trump would issue orders that caused an even bigger crisis. For a minimum of three more years, the head of the US government is rabidly devoted to the rule of law and there will be no doubt what the response will be.
This ignores the fact that in this country partisan tensions almost always decrease, not increase, during a major conflict. This is likely to be even more true in this case than it would in most, because so many of the attacks on Biden are groundless claims of senility and equally groundless charges that he's incapable of decisive action. Both would be obviated by an active conflict - he's been warning against continued aggression from Russia and China for years, and standing up to that aggression is about as decisive as it gets.
