Left isn't rising as you think. The right is clearly gaining more momentum in the Europe.
In Asia, there has been increasing tilt towards nationalism like in India, Indonesia, Japan. S. Korea is left tilt but it's more of an exception than a norm.
Anti-imperialism, anti-colonialism and marxism breached their way into normie territories in the last two years. And Climate change is radicalizing people EVEN MORE.
I'm not kidding when I tell you that the planet is splitting in two very distinct and international sides.
We are close to a complete war, but we are also close to a great awakening.
Also, even if Europe do get left in power, don't even expect any cordial relations with China. India and USA doesn't want EU - China close relationship.
China is the undisputed winner.
Trump still has atomic bombs and leverage tho, which makes him dangerous
EU doesn't trust China
French leftist - if they arrive to power and if they manage to resist the power of the EU - will be leading the movement and LFI is not against China. And radical will push to seek an anticapitalist partership with the CCP, we have no interest in fighting China at the moment.
The middle east will align on anti-imperialist interests and Putin will be a wild card.
