I can't speak for the UK but in Canada we prefer ineffective governments. A politician who breaks his promises is by far preferable to one who keeps stupid promises.
Whenever there's a debate about voting reform in the UK, one of the arguments people use to defend the first-past-the-post system is that it increases the chance of parties getting a significant parliamentary majority (even without a significant majority of votes), and thus means they can effectively implement their policy programme.
I still haven't figured out why that's supposed to be a positive.
She has the constitutional power but it is socially unacceptable for her to use them.
It's not about social acceptability - she does not have the constitutional powers you think she has. The Queen's authority to dissolve Parliament was formally abolished by the Fixed-term Parliaments Act (2011).
She does have the theoretical power to dismiss May, but not to dissolve Parliament.
It looks like May might have finally caved to the Customs Union. That option had the strongest support among indicative votes. So maybe she realizes that is the only way forward. It is annoying the strident Brexiteers. But since it has the best chance of solving the Irish border problem, if she can get the moderate conservatives, Labour and the DUP to jump on board, that may be enough to get her plan across the finish line.
EU: Sure. Take a couple years. We're not the ones going. We'll be right here. Let us know when you're ready. In the mean time, everything's cool. No problem you guys voting in our election. After all, y'aint left yet. You're still one of us. Kisses.
I'm sitting at a computer terminal in a public library in the middle of nowhere - a.k.a. Canada. Somebody left a Zwei Euro Cent coin on the table. It's similar to a Canadian 1 Cent coin, which no longer exists. For me, this is the most interesting thing that has happened in the history of the EU.
