Do international alliances always make the world safer, or can they sometimes lead to more tension?

“A mind unfettered in deliberation” is the NATO motto. NATO is my favorite topic. My big question is “Do international alliances always make the world safer,or can they sometimes lead to more tension?’. I think that alliances can lead to world peace but are more likely to cause extra tension.

Lets say we were in alliance with Russia and we got into an argument. We then cut off all international aid and it caused tension with our other alliances who were also in alliance with Russia. This isnt gonna help with world peace. We can also imagine we’re in alliance with China and they needed help so we sent over money. This can help cause world peace by helping a country in need. We can even pretend that we are in alliance with Burundi and they needed money to build new shelters and prepare for a storm. We didn't send the money and 100,000 people died. This causes a lot of tension because all our other alliances think we are a selfish nation,which isnt a good look to help cause world peace at all.

Someone with a different perspective may feel like its a half and half situation but I think they are wrong. The reason I feel this way is because there are more things you can do to cause tension than to cause world peace.

To conclude, alliances can lead to tension,but there is a slight chance that they lead to world peace.
