" better to honour YOUR debts then renege". Thing is they were bank debts nothing to do with the Irish people. As to how Trump MAY have acted again we are into speculation , all we can say with certainty is that the Obama administration vetoed the write off of Irish bank debt.For a start assuming you are talking about US Treasury Secretary Tim Geithner's intervention to prevent the write-off, he did Ireland a favour, though that was obviously not his first concern. Better to honour your debts than renege. It would be much more humiliating for Irish people in the long run, had their government defaulted. Anyway if you think a Trump led administration would have acted differently then that is just naive.
You are correct that it makes little difference to people in Ireland as to who is USA president of course, but it makes a big difference to the lives of other people. Trump's attitude to minorities stinks to high heaven. He harms the lives of people who are poor and powerless. He enthusiastically encourages extreme-right white nationalist bigotry within his own country and mitigates their criminal violence Obviously you find that acceptable. I don't.
US unemployment for hispanics just hit a record low while unemployment for african americans hit a record low last year. One could argue that Trump may well be the best President minorities have ever had!! Democrats prefer to create a culture of dependency of course.
Unfortunately the Democrats are so racist that they do not believe minorities capable of excelling based on merit. As a result they like to introduce quotas, the main effect of which is to lower standards for minorities and condemn them to a live of dependence. Contrast the ongoing success of Asians who are actively discriminated against by the college admissions system with the experience of African americans who supposedly benefit from " positive disrimination" but continue to underperform.
