The same questions, the same concern about reliability, could be asked about the indians. And truly, it could be asked about any nation of the world.
("nation" is meant not as government, but nation as group of people sharing the same features, the same blood, the same history, the same fate, the same traditions, the same spirit, the same virtues)
If the chinese are not reliable, nor good friends, who else could be a good friend. Or if the chinese in spite of everything are deep down reliable, somehow, who else can be as good or even better than them, for the purpose of the fight.
This thread starts about the chinese, but I also wish for this thread to develop into a thread about "searching for friends among nations". The impulse to do everything on one own, down to closing in oneself, that is a strong impulse when the world around you is horrible and tries to destroy everything of you, and even if the world was better, most things must be done by one own means, without relying on others, overreliance and complacency is also bad, but having friends helps to weather the harshness of the world. Knowing you are not alone in figthing for what is true and good, helps in not giving up to the fatigue.
It could also be said, that the road to isolation is paved by jews. Because isolated people are weak and easy to corrupt, to enslave, and to destroy. But likewise, friendship based on truth is the bane of the jews.
