The question of whether NATO enlargement is a good thing is a complex one, with strong arguments on both sides. Some people believe that it strengthens the alliance and deters potential aggressors, while others believe that it provokes Russia and increases the risk of conflict.

One of the main arguments in favor of NATO enlargement is that it strengthens the alliance by adding new members with capable militaries. This can be seen as a deterrent to potential aggressors, who may be less likely to attack a country that is backed by the collective military might of NATO. Additionally, enlargement can help to promote stability and democracy in newly-joined countries, as they are required to meet certain democratic and human rights standards before they can be admitted.

However, there are also strong arguments against NATO enlargement. Some argue that it provokes Russia, which sees the alliance as a threat to its security interests. This is especially true in the case of former Soviet bloc countries joining NATO, as Russia views these countries as part of its sphere of influence. Additionally, enlargement can increase the risk of conflict, as it can lead to a situation where two opposing military alliances are facing each other over a disputed territory.

Ultimately, the question of whether NATO enlargement is a good thing is a complex one, with no easy answer. There are strong arguments on both sides, and the decision of whether or not to enlarge the alliance is a difficult one that must be made on a case-by-case basis.
