The North Atlantic Treaty Organization (NATO) is a military and political alliance used to guarantee each of its members' security and freedom. Created after World War II, the goal of NATO is to promote democratic values, co-operate on defence and security issues, and to build trust among members. This, in turn, helps prevent conflict from occurring. NATO also promotes a peaceful resolution of disputes. However, if diplomatic efforts do not work, the military alliance is used for crisis-management operations.

During the 2014 NATO summit, all members agreed to spend 2 per cent of their GDPs on defence by 2025. However, according to data gathered in 2017, many nations still fall short of this threshold. For example, Germany still won't be at 2 per cent of their GDP spend in 2024, for example. And quite simply, this isn't on - especially when poorer NATO members such as Greece and Poland are pulling their weight.

As of 2019, there are 29 members of NATO. Those nations include:

Albania, Belgium, Bulgaria, Canada, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Turkey, United Kingdom, United States.

The United Kingdom, along with the United States and Greece are the only three nations to exceed their 2 per cent spend, while Poland also meet the goal by spending 2 per cent precisely.

So, no we shouldn't be expected to defend other countries who aren't doing anything to help themselves!
