I read a very interesting article recently that showed me how the strength of the different countries is largely influenced by the prevailing meta. Here is a link to the article.

The article mentions how long ago a bounce in the channel was the most common opening for England and France. But since this was a bad opening for France though later on French players offered to support England into Belgium in exchange for an empty channel.
Many people view France as the strongest country in diplomacy and I think that might be related to the later change in meta.
After thinking about it I'm surprised the meta is the way it is today. The vast majority of English players today leave the channel open without anything in exchange and often allow France to get 3 builds with no opposition while England likely gets one. This is clearly a bad strategy and deal for England.
I don't think asking for a bounce in the channel or making any demands is a good idea for England.
But what if England said to France, hello France, if I open to North and Norwegian Sea would you be willing to support me into Belgium?
If France doesn't say yes then just move to the channel and either support yourself into Belgium or make an attack on Brest. This will put you in a very good defensive position, certainly much better than the alternative.
If the meta changes so that French players have to offer England support into Belgium in exchange for a DMZ of the channel, England will be become a somewhat stronger power while will become a somewhat weaker power.
Even if the French player goes back on their word and bounces you out of Belgium they're still limited to two builds and you could point out to others how untrustworthy they are.
My point of view is that England should not leave the channel open without getting something in exchange such as Belgium.
Another possibility is asking France to promise not to build a fleet in Brest but if France gets 3 builds and goes back on their promise they're in an excellent position to stab you.
A 3 build France in 1901 is very dangerous to England. A common French strategy is to build two fleets, get those fleets into the MAO and Irish Sea and then convoy an army from Gascony onto the island.
As I said I don't think it's a good idea for England to demand Belgium or ask for a bounce but I think it's a good idea to ask France if they're willing to support you into Belgium in exchange for the DMZ and if they don't say yes I think you are better off of moving to the channel and supporting yourself into Belgium.
I'm curious about others thoughts. What do you think is a good course of action for England in the early game?
