Former President Donald Trump is changing world rules. He is talking to old friends differently. He also told a neighbor country about money problems. He will let a rival country have important technology. These actions are strong. World leaders are surprised.
Trump thinks some European countries do not help enough. This is for the war in Ukraine. He says they "talk but do not make things." Europe leaders say they help Ukraine. President Zelensky wants to work together.
Trump also spoke to Mexico. They talked about water. Trump said Mexico does not send enough water. He said he will tax Mexican things if they don't send water. This makes problems for the two countries.
America will let China buy AI chips. This is a big change. The government is making new rules. Nvidia can now send chips to China. Some people think this is good for business.
But, some people are worried. They worry China can use this technology for its army. They also worry China can watch its people. They think business is more important than safety. This could make America's technology weaker.
These actions use money and trade to show strength. But they can also make problems with friends. It is not clear if these actions will help.
