China already said it will answer accordingly with economical and military means.
In the case china allies with russia - which is highly likely based on geo-strategical positions - what are the chances that trump will be succesful?
There are stories of china talking indirectly with trump through jack ma who promised to create 1 million jobs in the US in the next coming 4-8 years, but isnt this more or less just a drop of water on a hot stone?
Your raising the only important fact about Trump.
USA is a warmonger country. They have never built anything FOR their country but rather AGAINST an enemy.
They need to feel threatened in order to go forth.
That's a pity but that's also a fact. That's why they never have been at peace.
Enemy was Russia. Then it became Middle East. And now Trump points at a new enemy: China.
