Hi Clive,
Yes, I can see it that way, too. But in that case I want to leave
out the "twenty years" phrase and substitute something else.
"..., yet a powerful municipal will eventually made the boast a reality".
For me, the "twenty years" phrase exerts a strong feeling that we need "
had made". Is it the suggestion of
having
worked for twenty years that leads us there? Leads us to prefer
the perfect? Hmmm. On the other hand, maybe that's not what
your instinct is telling you. Just thought I'd mention it.
