The United States will get weaker and weaker every day that Biden (or probably any ‘rat) is in office. Furthermore, times of transition are optional to attack the US... very much like Bin Laden did after 8 years of Clinton negligence turned into the GWB transition. There’s no rush. It’s only getting better for China for 4, maybe 8 years.

There is a rush. Conquest takes time, and USA has relatively rapid turnover of leadership. Our mentally ill President may be replaced at any time by someone more capable and decisive - and someone who had zero support, so will be running scared & decisive. There’s at best 6 months of Biden, the best time to coordinate multiple conquests (with Russia & others) to flummox USA with a multi-front conflict. After that is at most 3 years (maybe 7 but unlikely) of weak Kamala. Come 2025 any conquests best be completed so a strong leader (Trump?) cannot interfere.
The time for world dictatorial conquest is now. I’ve long wondered when tyrants would coordinate their expansion, and now the time and two major powers seem keen on doing exactly that - watch for others piling on the bandwagon while Mr Malarkey fondles women in public.
