We must make ourselves ready.
Legally, by law:
10 U.S. Code ยง 246 - Militia
The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard.
No question the time is now. Problem is we need leadership!!
I'm going to have to gently ignore that age discrimination you're quoting.
..not to mention various Rules of Engagement and Play Nice treaties.
