How should I parse the part that comes after 許さない:

> その形容から打突こそ主体と思われるが、槍｛やり｝の基本戦術は払いにある
> (1)。長さに物を言わせた広範囲の薙｛な｝ぎ払いは、もとより身を引いて躱｛かわ｝す、などという防御を許さない **からだ** (2)。

Feels like it makes the sentence flow a bit better with sentence topic but
what is it, exactly? から_だ? から used to affirm what's stated in (1) + copula for
emphasis?

question
grammar syntax
How is からだ used here?
「～～からだ」＝「～～からである」＝「～～からです」

> "から used to affirm what's stated in (1) + copula for emphasis?"

Kind of but not quite. It affirms a prior statement by explaining the reason
and/or logic behind the content of the prior statement.

The copula is **not** there for emphasis. It is just needed there for the
grammar reason. In informal speech, it can be dropped and you could end a
sentence with 「から」.

Statement #2 explains why the sweeping is the core of the spear fighting
instead of the attacks.
