It has been widely felt by those dealing with the affairs of Britain and USA that the two most prominent events of last year, namely, Brexit and the USA Presidential Election has resulted in much alienation on the part of these two major economies thereby creating an image which is of being less friendly to the outer world. Question is, the present trend is here to stay or would it give way to a better situation in future?
Historically, US and UK have very close allias and work very well s partners.
We will see much more national protectionism in the coming years.
The outcome of any major political shift is difficult to anticipate, and we mainly depend on informed guesses. The economic pressure of global competition on very crowded markets and the quest for employment, since the Soviet collapse (~30 years ago), seems to guide the political classes of many nations to rethink and readjust their policy options, concerning 'free' trade markets, competition and national survival in the global arena, with respect to 'native' populations (i.e. the voters, taxpayers and citizens of a given country or polity).
The history is ideological weapon! As shows history they are always in the same boat.
