Azerbaijan is also a small country, although it's correctly painted as the bigger and richer of the enemies in this conflict. Additionally, Azeris and Armenians hate each other. So Azerbaijan is too small, weak and culturally different to subsume Armenia.

The big powers in the region are Russia, Turkey and Iran. If you must argue that Armenia should pick a big power to cosy up to, those are the options. Turkey is likely committed to Azerbaijan, but Iran and Russia are willing to play both sides.

Pursuing closer links with Europe and the EU is a fourth option. As the article points out, Armenia has historic links to Europe (although in the same paragraph it concedes that the strongest of those are to Russia, not the Western countries...) and this would be more attractive to Armenians. Unfortunately, it doesn't have much to offer the EU. It's poor and geographically isolated and the EU, which doesn't have unified armed forces, isn't interested in projecting military power overseas.
