They7 will not fight by shipping over an army by boat across the ocean.
They will first infiltrate the country by sending thousand (or millions) of military-age men across our borders. Until they have a standing army in place.
And they will get the USA to pay for it, and support them.
I just finished a chapter in Robert D. Kaplan’s’ “Imperial Grunts the American military on the ground.” Special forces were doing a low-key good job in the P.I. winning hearts and minds in the war against muslims. The P.I. military is corrupt with the NCO class being very pathetic. The other motivation is setting up a HQ for a potential war with the Chicoms. Kaplan’s books are excellent.
