NATO was never about invading another country. It's purely intended to be a defensive pact (the whole Kosovo incident in the 90s notwithstanding). And that wasn't exactly Europe's response to Trump. Defense spending by European nations had been increasing since 2014 but a number of countries still did not meet their internal agreed-upon goal of 2% of GDP.

Trump wanted to raise it to 4%.
