Is it safer for a country to have many different allies or to rely on one very powerful relationship?

I think it is safer for a country to have many different allies than to rely on only one very powerful relationship because, what if one day the country and the very powerful country get into an argument and become enemies? then the country relying on one powerful ally would have nobody to protect it and stand against it's side and it would also be very vulnerable to attacks made by the more powerful country.

Usually many different allies can generally provide a safer and more long term stability, while only having one powerful relatioship can offer imediate high level security and protection incase of a enemy attack, plus if one relationship breaks down in a group ally, then you can have multiple choices and backups still, while if the very powerful ally breaks down, then the more dependent country has no other allies to help and keep them safe. Having multiple allies can also increase the cost of aggresion for any possible attackers, acting as a giant and powerful shield for defense against enemies, guaranteeing high level security and long term stability, althought having one powerful ally can provide imediete and powrful protection such as millitary power or aids when in need of them, plus having one relationship is easier to manage than multiple, sometimes messy relationship.

In conclusion, it is better and safer for a country to have multiple relationships with different allies than one relying on one powerful relationship, because it can make the countries less dependent while still being able to ask for help when in dark times. However a single relationship can also provide more protection and higher levels of security althought if anything does happen to that country, the more dependent country could have no other allies to turn to, becoming more vulnerable in attacks.
