Just repeating the same words won't work,because it appears you can't really explain history. Most of the same lot and their descendants are still around. Just repeating the Democrats are anti-British,and the Republicans are 100% pro-British is rubbish.
Going back to 1900,when Republicans(before neo-cons existed) still supported the Irish, shows the Republicans are as "anti-British" as the Democrats are. Why should they care,when many of them are also thinking of Irish American votes in their own country? A Republican president(Eisenhower) caused the fall of Eden's government in 1956. You have zero answers for this.
You also are believing 100% what Trump told you?? You mean the same Trump,who will show how pro-British he is,the second we disagree with him,and changes what he says from day to day. Like when he threatened the UK with no trade deal,if we didn't follow his views on Huawei,etc and ban them.
The same Trump who flip-flopped on saying the NHS should be part of any trade deal,despite the electorate not really wanting this??
Or the same Trump who is putting pressure on us(and the French),on trying to tax US megacorps profits in our shores??
You can't keep saying foreign interests are "anti-British" - they are pro their own interests. Sadly,because of history it just happens that Ireland happens to be in their own interests too.
Also,why would we want to go back to the Troubles?? Is the lives of 1000s of our soldiers and civilians not enough,to actually make this feckless,not stop and think. At least you are OK,as you live somewhere else!
