What I find passing strange is that for many events (such as the SCW) CORE does provide more than one option, with a major dissent penalty for deviating from the historical ('A') choice. Even if it's unlikely (to the point of swallowing a 10 or even 20 dissent, as you do with the B and C options for SCW), there should be some alternatives. Most players won't choose to go that route (discouragement is what the serious dissent penalties are for), but the option should exist, however unpalatable it's made to the player. Sure, it might be boring to crush an unprepared Germany in late '38 or early '39, but it's rarely a bad thing to give players more choices to decide upon. Besides, if it's allowed for the French or the Soviets to go to war with Germany in 1936, is it so bad to allow the UK some chance in 1938 to stand up to Herr Corporal?
As for ENG beginning at Intervention 6, there are various random and nonrandom events that can shove the slider towards isolationism. Even without such problems (I got hit by one of those involuntary isolationist slider shifts, which forced me to reload the game from a point months earlier), you'll still need to move the slider yourself by at least 1 towards intervention in the prewar years if one wishes to help Poland in Sep '39. 6 + 2 (for GoI to Poland) is 8, and you need 9 for the DoW, thus the +1 shift players must make themselves.
