how can buddhism affect change on powerful countries that use war to gain political and or economic advantage ​

Buddhism is a religion that seeks to avoid conflict and harm. Most buddhist monks, for example, are vegetarians or vegans, because they desire to avoid harming animals.

Besides, Buddhism is a nihilistic religion, so it would see the objective of gaining more power by the means of war, or any other method, as meaningless in itself.

In conclusion, Buddhism is a nihilistic and peaceful religion that can teach countries a lot about avoiding war and solving conflict.
