Well who in his right mind would invade Ireland . There's no natural resources worth the name nor are the locals there to be considered resources or resourceful by any yardstick.
The only way one can exploit Ireland is to take over the land & reduce the locals there to tenant farmers . Basically it's harking back to what the English Scotsmen & Welsh did to the Paddys there over the past 7-8 centuries ending last century & something I suspect the Brits would be contemplating once the after effects of Brexit are truly felt beginning next decade. Isn't it Paddy ?
