It is a matter of record that Menzies Campbell had wanted to support the Iraq War, but Charles Kennedy stopped him. Paddy Ashdown supported it, and the Lib Dems had of course pioneered support for neocon wars under him, enthusiastically cheering on the dismemberment of Yugoslavia.
Together with the neoliberal economics that leads to it and which provides its only rationale, neconservative geopolitics is the coming force among the Lib Dems, along with Euroscepticism (jolly good, though incompatible with neoliberal economics or neoconservative geopolitics).
And, I confidently predict, along with opposition to the former Holy Grail of the Single Transferable Vote for multimember constituencies (again, jolly good), as the penny drops about just how ill-served the Lib Dem heartlands of the West Country, the North and South of Scotland, and Mid-Wales would be by such a system.
It is also possible that Highland, Island, Border and Mid-Welsh disaffection with the Central Scottish Parliament and the South Welsh Assembly, as well as the Alliance Party's disaffection with the DUP-Sinn Fein carve-up at Stormont, might turn the Lib Dems into (jolly good) hardline Unionists.
All in all, the Lib Dems as we have known them are finished.
