Maybe we should stop providing Southern Ireland our military air and navel support as defence. Let some EU country do that for them. We only do it to suit ourselves as it's land close to our borders and also there's the Noth Atlantic communications cable, including internet that crosses from the West coast of S Ireland to the US. Things could get very interesting if France for example stood in on behalf of the EU to provide a QRA over S Ireland instead
The republic is a neutral country, as you say any military assistance is carried for mutual benefit so why would we stop ?
You have a very weird world view
