Whatever the outcome of the legal battles around president Trump's immigration order, there can be no doubt that there is going to be a vigorous campaign to deport as many illegal immigrants as possible from the USA. It has already started http://dld.bz/fyg7X. No doubt it will get more and more thorough and more and more people will actually be deported. Jolly good thing, some will say. After all what is the point of having laws if nobody takes any notice of them (though, of course, many south European countries have been operating this way for centuries). However, this is going to result in a lot of disgruntled people arriving back in S American countries full of fury at the US. Latin America is the US's "backyard". It is also, as some Spanish speaking people are wont to point out, the "other" (dare we still say "alternative") America. Although it is still part of the "second world" we are not here talking about somewhere insignificant. So far, the US has only had real trouble from that continent in Cuba and Venezuela. I wonder what the future holds?
Not only abroad. Within the US these actions are going to precipitate a kind of internal "war" between those citizens who do and who don't sympathise with the immigrants. Those who do do so include both hispanic people (who may now start to withdraw co-operation with the authorities thus making American cities less easy to govern and even, perhaps, providing a new seedbed for organised crime) and non-hispanic people who may now feel themselves in more serious conflict with the government to a degree that may in due course dwarf previous civil rights disturbances. If to this is added a further crack down upon black communities, civil order is going to become extremely difficult to maintain. American cities could become jungles as bad as they were in the 1930's or worse.
It is understandable that there would be a white backlash given the demographic trends that, if unchecked, suggest they are heading toward a situation where they will become a minority in what they regard as their own country, but changing such trends is not at all easy even if it were desirable. It involves real conflict. Such conflicts in which both sides feel themselves to be totally justified are not at all easy to resolve and the collateral damage can be considerable.
When there is mounting strife at home, it is quite common for governments to use the strategy of fermenting a confrontation with an outside power as the only way of bring unity back to the home population. I hope it does not go this way this time, but one can rather see it coming. I do not think I am alone in thinking that the world is currently becoming a more dangerous place.
