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

My big question was ‘’Do international alliances always make the world safer, or can they sometimes lead to more tension?’’ It depends on the country. I believe that it does make the world safer due to the fact that they would trust each other. Tell me, would you join an international alliance if you didn’t trust one of the members in it? I wouldn’t. Which is exactly why I do think it would make the world safer. No country would join it unless they trust that none of the other alliances do something out of line like that over the other alliance which would not be okay for the rest and would start something that no one wants to happen. This is why I believe that it will make the world safer.

However, people do think that it won’t always make it safer. Now, I don’t disagree but it depends on the country. Some would bring in Trump and all the things he's doing in the world right now. Trump created a major diplomatic standoff by pursuing the annexation of Greenland(according to trendsreseach.org), a territory of NATO ally Denmark. He refused to rule out the use of military force and threatened 25% tariffs on European allies who opposed the move. This move did make the other counties disappointed by the decision. But none wanted to get more tariffs on it since most of their business comes from the US.

However, Trump is one person, it doesn’t mean the world isn’t safe. Having an international alliance means every country has a different point of view, so Trump wouldn’t make the world not ‘’safe’’. But he is close to taring it abit.

So to me I believe that it does make the world safer due to the many different points of views, and many smart minds trying to solve problems and conflicts. 70 years of conflicts not reaching WW3 is due to NATO solving other countries' conflicts beause of many alliances working together to solve these problems.
