But we would like for an attempt at 2%.
Nah, we much rather spend the money on stuff like meals on wheels and broad availability of education. As we can see in the United States, lack of the latter is the by far biggest threat to a nation state.
To be honest it would make the alliance such . Smaller conflicts could be heeded off without mass intervention by dozens of states (think Libya, Sudan, Piracy problem off east Africa).
You mean like the awesome successes Iraq and Afghanistan have been?
Larger countries like Russia and China would be faced with much more complex and adaptable adversaries
Russia is a non issue, they have a tiny economy that isn't able to make any significant export product able to compete in globalised markets beyond the technology of sawed wood. Countries pick decades old F16 over modern Russian offerings if they can get it and afford it.
And if you want to do something about China, that is ever easier: stop buying stuff made in China
But President Trump pushes to euthanize tens of thousands of US citizens to give a trillion to the rich, which will, like in the past, invest it in China and Vietnam to put americans out of jobs.
In a very real sense he is cutting your health care to prop up the Chinese military.
Heck, Trump and his favourite Junta, like all Republicans he loves communist labor camps, are so close now, the Chinese even make people disappear that investigate how terrible the working conditions for his wife's workers are....
Plus European states would have more say in where the resources are spent.
You mean more than the 100% say we have in it now?
