The United States has said yes to Ukraine using big missiles that can go very far. This is a big change. The president of the United States, Joe Biden, made this choice. But soon, Donald Trump will become the president. He has said he wants to stop the war between Russia and Ukraine.

Russia is not happy about the United States' choice. They say if Ukraine uses these missiles to hit inside Russia, it will be like the United States is fighting against Russia. The president of Russia, Vladimir Putin, has not said anything about this yet. But a person who speaks for him said the United States is making things worse.

The war between Russia and Ukraine has been going on for a long time. Both sides are fighting hard and not much is changing. The United States thinks that by letting Ukraine use these big missiles, it will show Russia that they cannot win by fighting. The president of Ukraine, Volodymyr Zelensky, says the missiles will show what they can do without needing to talk about it.
