> decent parliamentary system.
Isn't that an oxymoron? Parliaments have their democratic shortcomings compared to powerful presidents. And vice-versa. Nations with parliamentary rule are plagued by having heads of state and ministers which weren't in any way, shape, or form elected by the population. A president is at least a democratically elected ruler to represent the people.
Parliamentary democracy has a far better track record than presidential systems. Basically all presidential democracies are shit have had had huge problems, except maybe the USA, which is of course no longer even really a western country any more.
