Well, yeah, but like I said, the vast majority of Austrian players never seriously consider an alliance with Turkey. Save for a few shining beacons of openness to new ideas, the only time where I've ever seen Austria ally with my Turkey is out of absolute necessity (there is a known and very open Russia-Italy alliance with no real hope of a Western Triple to pressure Russia and/or Italy). And it doesn't matter what I offer, Austria just doesn't listen to me and goes through with it.
I think the people who insist that Austria should throw all her centers to Russia and Turkey the instant Italy attacks -- and there are many who have written widely-circulated articles on the subject -- are to blame, as are the "OH MY GOD JUGGERNAUT" crowd. Italy has effectively three options for an opening: France, Austria, or Turkey. Given the aforementioned attitude Austria takes toward Italy, Italy is almost doomed to fail at any attack on Austria unless his diplomatic work is extremely thorough and impressive and backed by very strong tactical play. Russia tends to ally with whichever of Italy or Turkey comes out stronger in a carveup of Austria, because if Italy is the odd man out then Russia can leave his strong neighbor alone for a while to get the builds from England/Germany/etc. to get ready to fight Turkey, and if Turkey is the odd man out, Russia can delay the northern campaign until he and Italy KO Turkey and get builds with which to push west. So unless Italy has done an extremely good job in attacking Austria, an attack on Austria doesn't work long-term.
That leaves France or Turkey. And the only way France works is if England and Germany are on board. This can work, but it takes as much effort to succeed as with Austria -- not because Italy will get steamrolled by EG afterward, necessarily (though it could), but rather because in all of this Italy has to keep Austria and/or Turkey from chipping away at its back side. Plus, EG don't always go after France, and if you only have the help of one then it's likely that the other is on France's side instead, and your attack isn't going to work. France isn't suicidal, but the stats Tru Ninja compiled are pretty clear -- the anti-French openings are statistically much weaker than Italy's other options.
Which leaves Turkey. Italy is as stuck as Turkey is.
And why? Because Austria swears mutually assured destruction if Italy doesn't ally with him. And enough people have done it over the course of however many years this game has been played that Italy knows it's coming.
My question now is again why, but a step back -- why should Austria be so quick to push the red button? In no other neighbor dynamic do you see this on such a consistent basis. Putting aside the rabid vendetta players who do this to everyone all the time as a strategy, you never see, for example, France swear mutually assured destruction to an England who enters the Channel, Germany swear it to a Russian in Silesia, etc. If England attacks France, then sure, France rallies Russia and Germany to its cause (or tries), but France doesn't go "Okay, giving Germany all my stuff, have fun." Germany will try to ally with England/Austria/Turkey, but only as a last resort would Germany give all its centers to England and France.
As a strategy, it's stupid. Austria dies first, Italy second, when Austria could simply behave like everyone else and try to stay afloat and actually make friends with Russia and/or Turkey to beat back Italy. When Austria DOES do that, it actually manages to survive more often than one might think. (And of course when Austria does that, I'm Italy attacking Austria, and I get my ass kicked. Go figure.) But as a meta-strategy, it's great, because now Italy is stuck, forcing Turkey to be at Austria's mercy. (I'm rather surprised the Austria-Russia alliance isn't more popular here; it's ridiculously successful whenever I see it played, and it's not like Turkey and Italy ever seriously consider anything but beating each other into oblivion anyway.)
I realize I'm going on for a while at this point, but I think Italy's and Turkey's issues are rather closely related.
