@Mn-guy As your question is neither about the website nor the forum itself I have moved your topic to the A&A Classic Forum Category,
Is Eire and United Kingdom adjacent by land …
No.
… or you need a transport between the two?
Yes.
Yeah, I would suggest taking Hawaii, Alaska, and maybe even WUSA (i’ve seen this happen). Disruption tactics are a must when dealing with USA in order to help in a Germans. What you want to do is frighten the USA in at least keeping a garrison in their home country. This gives Germans more time to prepare for a possible WE invasion. If USA doesn’t fall for the bait, then congrats, you now have a steady source of income. :)
