Those nations are far from neutral though. Each one of those nation's is a member of at least one major military alliance.
Yes
That's why I said: "some kind of neutrality"
Meaning not neutrality by ignoring, isolationism for reality or neglect.
Some kind of neutrality would indeed be an interesting option.
I think Japan, Canada, Australia could be good examples.
I think neutrality is an area on one side of the scale.
Looking back at the "neutral" countries in Europe during that full blown war WW2... most of them were involved in some way.
So again yes to what you say with those alliances, and I take an alliance as the NATO very seriously, like my government.
How you stand in such an alliance, how you stand outside the prime reason for that alliance, especially how you weight in UN resolutions, gives still a huge room for positioning in real terms (like military) and influencing terms (like silent diplomacy, economical positions, generous humanitarian actions and aid, and statements for the public newsmedia).
Taking international law, and widely supported UN resolutions seriously, makes it almost impossible to be fully neutral. Not doing something as much not-neutral as doing something.
"neutrality" can be very active... and the effect of any small steering signal is most effective if done fast, whether silent or in public.
Is a matter of political style and culture of the involved country as well, domestic and foreign.
Countries and their peoples do differ there in style, also when they agree on the objectives.
Countries, their politicians and their civil services do differ in professionality and the way they act and how effective that is, also when they agree on the objectives.
Trump's strategy regarding Iran has a forcing character... lessening the room for all the grey shades, forcing binary loyalties.
Erdogan is doing the same. Whether with those S-400 or Cyprus gas drilling. Betting the house of his NATO and EU relations.
