NATO
The expansion of NATO is dangerous. By keeping the alliance growing, there are other nation states who see the need to strengthen their defences in opposition to NATO power. We see Russia ally themselves with China and North-Korea and the Arab world is also joining with Russia. They will build up their forces as a direct response to the proliferation of NATO and this is detrimental to world peace. NATO’s expansion is a direct reason why the power balance in the world is changing for the worse. This organisation is biting’s it’s own tail, while getting more and more enemies.
