For now there's a bit more, um, special courage powder floating around Parliament than Congress. Really we're lucky that the Biden team seem to have GOT THIS, most Democrats are behaving (but not all!), and the Republicans are still not completely sure if Putin is good or bad. UK Labour politicians are trying to start WWIII, so it's good they aren't in charge.
Humiliating bunker death might be deserved, but its inevitability does not necessarily provide a particularly helpful incentive structure!
