In terms of sheer military might, the size of Israel’s military is very substantial compared to the listed countries. Other countries would likely come to their defense if it happened, but if it came to a fight between Israel and just Norway/Ireland/Spain, it would be very hard to call Israel a small dog. Spain might be a bit of a challenge but Norway and Ireland would likely barely even register.
Obviously, all those countries have friends and are probably pretty safe because of that, but also not entirely idle threats.
That, and their leverage is pretty weak. Small dogs bark the loudest.

Israel has zero expeditionary capability, that is not how military conflict works.
