I don't think that anyone can tell you what you want to know.
Here is what would need to happen. All 3 countries (USA, Ireland, UK) would need to have removed travel restrictions both externally and internally. All the locations would need to be ready to resume typical tourist traffic. That could go two ways. First, the locations might still feel the risk of community transmission is too high and not want others coming. Or, they may be desperate to restart their economy and thankful for every tourist that comes.
Finally, you will need to feel comfortable that your risk factors would be low.
I don't know that anyone can predict with accuracy exactly what things will be like in mid-July.
