>Any country with some valuable economic or political resource and without nukes.

That reminds me of a very inspiring text that was written perhaps 200 years ago:

"I answered they [the causes of war] were innumerable, but I should only mention a few of the chief. Sometimes the Ambition of Princes, who never think they have Land or People enough to govern ...

"Difference in Opinions hath cost many Millions of Lives: For instance, whether Flesh be Bread, or Bread be Flesh; whether the Juice of a certain Berry be Blood or Wine; whether Whistling be Vice or a Virtue; whether it be better to kiss a post, or throw it into the Fire; ...

"Sometimes the Quarrel between two Princes is to which of them shall dispossess a third of his Dominions, where neither of them pretend to any Right. Sometimes one Prince quarreleth with another, for Fear the other should quarrel with him. Sometimes a War is entered upon, because the Enemy is too strong, and sometimes because he is too weak. Sometimes our Neighbours want the Things which we have, or have the Things which we want; and we both fight, till they take ours or give us theirs. ...

"For those Reasons, the Trade of a Soldier is held the most honourable of all others: Because a Soldier is a Yahoo hired to kill in cold Blood as many of his own Species, who have never offended him, as possibly he can."
