Why Ireland?
Ireland has some major advantages right now when it comes to chip investments.
Besides having a sizeable existing cluster, with the associated skills and infrastructure, it's politically in a great place for investment.
It's in the EU and while it's militarily neutral, it's very heavily aligned to the US.
The government is heavily pro Foreign Direct Investment and that's unlikely to change much even if Sinn Fein get into power. Due to the level of FDI in the country, it simply can't go nativist, it would be utterly catastrophic and as a small country, it knows it's nowhere close to being deluded enough to believe it can go it alone (c.f. Brexit).
As a result, it's unlikely to pose any particular problems from an export point of view, no matter what the geopolitical situation looks like.
There's fewer and few countries globally that are in the same position.
Tax situation is fairly handy too, but it's less beneficial for Intel than for companies like Google and Facebook
