The problem is that a few of the ragbag of independent attention-seekers are cabinet ministers and are using this for publicity/virtue-signalling. I would assume that the review will opt to retain the status quo, having pointed out the huge cost and inconvenience of doing anything else, plus the possible adverse effects on Irish undocumented in the US (for whom the same politicians always look for specially favourable treatment).
I get the impression that just about everywhere the protests against the immigration policy of the US administration is anti-Trump and not anti American. In Ireland however the Left will use this as an excuse to indulge in their usual anti-American nonsense.
I despise Trump, but the antics of the far left almost make me support him.
