It'a okay, but I think the part set off by commas (whether...) would be better before the "that."
That sentence is crazy long and would benefit from a rewrite.
The logical follow-on question then should be: What does this Islamic jihad mean to Americans? First and foremost it does not mean that we are necessarily at war with worldwide Islam. But it does means that, whether we admit it or not, Shari’a-allegiant Muslims throughout the world are at war with non-Islamic civilization, specifically including America and Israel, based on mandates in the Muslims’ sacred scripture, the Qur’an, and in Islamic law, the Shari’a as recorded in the classic manual of Reliance of the Traveller.

Is the underlined part grammatically correct, why or why not?

"But it does means that,"This is incorrect. The whole thing is badly written.

Hello,
1. Congratulations! You were right to question the grammar.
2. As you know, one always uses the so-called "base form" (bare infintitive) after do/ does/ did.
a. Therefore, "But it does mean." (NO "s.")
3. The gentleman or lady who wrote that made a mistake.
a. Earlier in the paragraph, s/he does follow the rule when writing:
"First and foremost, it does not mean that ...."

I missed the S entirely. I was looking at the "It does mean that" as an apparent contradiction to "it doesn't mean that".
After fixing the S issue, the "that" should still be moved to after the "whether" phrase.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
