Values of "would"
Here's the context (found it in a book): "The 7/7 bombings, as they came to be known, marked, symbolically at least, an abrupt end to the optimism of much of the Blair era. For slightly less than a decade, Britain had enjoyed a period of uninterrupted economic growth. That economic success had formed the bedrock of Tony Blair's election victories in 2001 and 2005. As Chancellor since 1997, Gordon Brown would (1) boast of having ended Britain's economic cylce of 'boom and bust'. But as Blair reluctantly handed over the premiership, the hubris of those boasts would (2) become clear. Britain would (3) face a series of crises over the next five years -- economic and political -- that would (4) result in the 2010 election being fought against a very different backdrop."
I do not think that I understand how the modal "would" is used here. In (1), I cannot decide between "repetition in the past" and "typical behaviour". Can (2) be a case of "reported future"? What about (3) and (4)? I would go for "events that you are not certain about", but I am rather confused. Is any of those four occurrences a case of conditional? Anyone?
