Think about it for a moment ... whether Trump's manoeuvres are intentional or not, the perception by China and Russia that the U.S. is less controllable [e.g. the U.S. will look after it's own interests first, damn the diplomatic 'niceties' & 'conventions'] will give the Chinese and Russians quite the pause for thought in their own manoeuvres and stratagems vis-a-vis their own national interests. China might be less-inclined to terrify its neighbours [South China Sea], and Russia might not act so arbitrarily n the next while [destabilizing Ukraine and the Baltic states].
