Ireland has been asked by the United Nations to act as an intermediary in the Iran nuclear negations between western nations and the Iranian regime.
As soon as Biden and the democrats took control of government one of their first acts was to apologize to Iran that the previous administration under trump pulled out, and they immediately sought to get back in the deal.
The problem now is the Iranians want more than they got in the original deal (which was a lot) these new demands have put many nations against a rock and a hard place since the previous administration under President Trump found they did not live up to the terms of the original deal.
