Diplomats meet for the U.N. General Assembly.

They say the world is in deep trouble.

Leaders and ministers talk about wars and economic problems.

They also talk about a changing world order.

U.N. Secretary-General António Guterres spoke.

He said leaders meet in a time of deep uncertainty.

He said power is shifting.

He said institutions must change too.

The past nine months brought big changes.

A U.S. military operation removed Venezuelan leader Nicolás Maduro.

Then Iran had a deadly crackdown on large protests.

Soon after, the U.S. and Israel attacked Tehran.

This started a wider conflict.

The conflict has closed a critical waterway.

The war between Russia and Ukraine also continues.

Both sides are attacking more.

Diplomacy is failing.

Other crises added more problems.

An Ebola outbreak hit the Democratic Republic of the Congo and Uganda.

This raised questions about pandemic readiness.

Earthquakes hit Venezuela and Colombia.

Floods hit Nepal and Tibet.

These events showed the effects of global warming.

Former U.S. Ambassador Robert Wood spoke.

He said the U.N. is at a turning point.

He said last year was bad.

He said this year is not much better.

A European diplomat and another official agreed.

They said the world is less stable than a year ago.

They pointed to attacks on international law.

They also pointed to failed mediation efforts.

Officials hope to use the meeting for talks.

They want to talk with rivals and allies.

One Gulf official said it would be good to have predictability again.

Slovenia's foreign minister, Tone Kajzer, also spoke.

He said interests stay the same.

But friendships and alliances change.
