This was bound to happen. The US has made a decision that this is the right time to rearm Japan.
Posters carrying a country flag should be careful about posting as each one of us represent our country's view to a degree.
At the same time, there are posters of varying credibility, so a single poster should not be used to get an impression about a country's official or even unofficial view.
The other thing to remember is that in this age of globalism every country in the globe trades with and invests in every other country. As we always have something to buy or sell from each other and money to invest to make profit.
But when it comes to military alliances or formal regional unions of nations, these are exclusive clubs of nations who have more in common within their group or have a common threat perception. Examples:
Military Alliance: NATO and NATO partners
Regional Union: EU, early in formation (ASEAN, EaEU, Arab League, African Union, UNASUR/Latin American Union etc.)
There are close economic cooperation between members of a Union and usually they are part of the same military alliance as well, but vice versa is not true, for example - Turkey is a member of NATO military alliance but not a member of EU.
NATO and NATO partners are not the last military alliance in the world, I believe there will be others. In a few decades, I think China will lead another military alliance. When that alliance takes shape, things will become clear about where everyone belongs.
Long term future possibilities:
SCO military alliance that may include the following possible unions:
- North East Asian Union (China+Japan+Korea's+Mongolia)
- EaEU (Eurasian Economic Union, former Soviet countries, except for the ones that join EU/NATO)
- ASEAN+Bangladesh+Sri Lanka
- West Asian Union (Turkey+Iran+Pakistan+Afghanistan+Shia 3rd of Iraq+Kurdish part of Iraq)
Current NATO and NATO partners:

If and when the new SCO alliance takes shape, over some years and decades, I think many existing NATO partners will join this new alliance. A di-polar world will thus come into being.
