The Austrians did a lot of fighting. From 13-16th century, Hungary was the bulwark against Turkey. From 16th to 18th century, Austria held the main line of defense. From the 18th century afterwards, Russia led the charge and practically destroyed the Ottoman Empire single handedly.

Ottoman decline was so rapid that Britain actually intervened to keep it alive and even fought Russia in the Crimean war to save the Turks. The British PM at the time was Disraeli, a '''catholic'''.

Not only did the West not help Austria in its dark times, France actually invaded Germany during the Great Turkish war, at the time the Germans and Poles were beating back the Turks. The Austrians had inflicted several crushing defeats and liberated all of Hungary. Had France not stabbed them in the back, its possible that Serbia and Romania would've been liberated a century ahead of time.

Its always Germans and Slavs saving Europe.
