Of course not. So NATO nations said they would but they really didn't mean it. Just an empty promise. Or in your words, "we'll try!"
NATO's pages state the U.S. will continue to spend the same amount regardless of whether or not the other NATO nations pull their weight? Really? You have to copy and paste that one for me. I didn't know NATO decides the military spending for the U.S. Please copy and paste this from the article you provided. I will be waiting.
