If you have been seeing the World News, you probably aware that Zelensky launch a drown attack on Putin and almost killed him.
Putin lost it and hit Ukraine with the largest drone and missile attack of war so far, killing not only soldiers by many civilians.
Even Trump has said Putin has changed. "I don't know what has happen to Putin, and I don't like it at all"
It's not the same Putin he knew just a few days ago. The concern now is that Zelensky doesn't seem to care if he starts a WW3 and takes the entire world with him.
The consensus is that if Putin had been killed, Russia would have launched Nuclear Bombs and wiped Ukraine. Then Europe would have launched Nukes at Russia,
Knowing this can happened, Germany is telling Ukraine to launch Missiles to Russia as soon as possible.
And that would be enough to tip the scale with India/Pakistan, Israel/Gaza(Iran), China/Taiwan
