Serbia, Libya, Iraq. NATO is NOT a defensive alliance,
Correct, but these countries are:
Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom and the United States. The other member countries are: Greece and Turkey (1952), Germany (1955), Spain (1982), the Czech Republic, Hungary and Poland (1999), Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia and Slovenia (2004), Albania and Croatia (2009), Montenegro (2017) and North Macedonia (2020).
So what's your point?
And while NATO may not have been involved, we fomented Islamic revolution in Egypt. I think the US oughta treying staying out of other people’s shit for ahile.
