Rules question - Whats the difference?

Hello All.

Can anyone GM included tell what the difference is between #230 AttEnmy and #235 AttNation?

The requirements are somewhat different but the blurbs are practically the same.

So what if any difference is there between them?

230 causes you to attack all enemy forces while 235 allows you to attack one nation. Or course the others are always free to attack you if they wish.

Handy to focus your efforts on the 1 army amid a babble that you know has the dragon or war machines, etc.
