How is it the moral lesson here? Is US even an ally? My country likes to l*ck Uncle Sam's bal*s. And just because Uncle Sam allows her to, she thinks he's an ally. We're a clueless, meek, nation. Perhaps the moral of the story should be to trust no one, depend on no one.
Self-sufficiency should be the goal. If we can produce for our own needs, if producers prefer the domestic market rather than the export market, perhaps a nation can sufficiently stand on its own feet. Maybe we can be the least affected of all these trade wars.
The hegemony of the US dollar has taken over many countries. My country, like yours, is quite heavily dependent on the States. An unpleasant situation? Yes, it is. But at this stage it is very difficult to change the vector of direction and become a completely independent country. Any state needs new technologies, and they are purchased from others. The time of global markets. This has been going on for many centuries and it is rather stupid to isolate yourself from the rest of the world.
To become a self-sufficient country, which is impossible in the current world, you have to go a very long way and, in addition, have geniuses in many areas in high positions. This is an impossible task.
