Will there be a third World War over Russia and Ukraine?

No, it's just bullying.

Talking about World War III is just political leverage to demand money for Ukraine and drive it into debt. No one will fight for her. All the advantages are lost. The United States has problems: elections are coming, Texas, the Houthis and Israel. Russia has gained a foothold in Ukraine, and the element of surprise has been missed. The sanctions are hitting Europe itself. Discontent is growing. The EU population is being ripped off, and industry is being exported. The EU has barely agreed on an extension of assistance to Ukraine, and there is no chance of agreeing on the start of the deployment of troops.

In 2025, with Trump's victory, the EU will remain alone with Ukraine. And eventually it will fall apart, because few people will want to spend money on Ukraine sacrificing the economies of their countries.

The political scientist explained why there will be no Third World War

Why is Elon Musk building so many rockets?

The future business of delivering goods to other planets

In the near future, the exploration of near space - the moon, Mars - will take place. The planets will be delivered cargo from Earth on rockets. The cheapest delivery is now through Elon Musk's SpaceX.

Since no country other than the United States has been mass-producing missiles, competitors will not appear soon.

Flew into history: how was Elon Musk's SpaceX able to overtake Roskosmos so much and so quickly?

Why are so many wars happening right now?

Because of the recession, because of the expectation of quick victories, because of ambitions

Sometimes war is used to distract from internal problems. The struggle for resources (oil, gas, water, rare metals) intensifies. This is especially noticeable in regions with unstable politics. Very often wars begin when a country's leadership believes that victory will be quick and cheap. For example, Russia-Ukraine. Sometimes countries start a war when they believe the international situation is favorable to them. Like the USA-Iran or USA-Venezuela. Regional conflicts and escalation. Like India-Pakistan, Israel-Gaza Strip, Cambodian-Thai conflict, Afghan-Pakistani war.

After the end of the Cold War in 1991, the world became less predictable. Previously, two superpowers — the United States of America and the Soviet Union — restrained each other. Now several centers of power are emerging: China, Russia, the USA, regional powers like Iran and Turkey. When forces are distributed among many players, there are usually more conflicts.
