So~that~ , intention or result?

Hello, everyone?

"That, of course, was the logic behind the establishment of the European Union: to so lock together the destinies of its nations, especially France and Germany, that they would have an overwhelming interest not to wage war again as they had done to such devastating cost in the first half of the twentieth century."

I have following questions;

1) where do I have to devide above sentence, at collon or the 'that', that is, the 'that clause' is a dependent part of 'to infinitive phrase' or not? (I guess it is a dependent one)
2) above 'that clause' expresses 'intention' or 'result'? (I guess it's 'result')
3) above 'would' expresses 'subjunctive' or 'past states'? (I guess it's 'past states')
4) if I replace above 'that' with 'in such a way that', then the original meaning still remains? (I guess it would be different)

Your valuable replies would be really appreciated.
