Yes now is the time especially wrt Iran and ruzzia. Irans proxies are significantly weakened in Syria and Lebanon. Russia also lost influence in Syria now that the freedom-loving people of Syria have risen up. Russia is also losing in Ukraine.
Either these countries buck up and accept the Rules Based Order or pay the consequences.
Sooner or later the civilized world is going to have to unite to take down racist fascist genocidal china too. It won't be pretty I admit but it's a small price to pay to prevent the downfall of humanity as we know it
