Hmmmm, I've asked this question myself a few times.
Since I live on the west coast I'll give it a try from the perspective of a Asia/Pac nation invading the west coast.
Let me set a scene on the fly, Open hostilities have erupted between the United States of America and the trans Asia-pacific Nation of the Peoples
Republic Of Sangese. Both countries have signed an agreement to not use Nuclear weapons.
Peoples Republic of Sangese
Capital: Owaking
Largest City: Owaking
Official language: Sangese
Government: Socialist State
President: Hu Bontaru
Premier: Macao Heung
Member of the UN Security Council.
Population: 420,000,000 (est)
Sangese Defense Liberation Forces
Military Age: 16-60
Available for military service: 90,000,000 (est)
Fit for Military service: 70,500,000
Population Eligible for Draft: 100,000,000
Active Duty Personnel: 2,000,000 (est)
Reserve Personnel: 3,000,000 (Fluctuates every two years due to youth 2 compulsory service before or after community college equavilant education)
Defense Budget (peace time): 800Billion USD
Defense Budget (wartime): 1.3Trillion (est)
Likely declarations of War to arise from
U.S./Republic of the Philippines (Mutual Defense Treaty, 1952)
U.S./Australia/New Zealand (ANZUS - U.S., 1952)
U.S./Republic of Korea (Mutual Defense Treaty, 1954)
U.S./Japan (Mutual Defense Treaty, 1960)
NATO
These Nations naval strength will be dealt with in Phase 1, neutralize their navy, but avoid any invasion/occupational type forces.
Grand Strategy
Phase 1- Engage the Third and Seventh Fleets and antagonize US intelligence with submarines raiding and sinking any US trade ships in the south
pacific. Move one or two fleet to guard Indonesia seas from other US Fleets. Third and Seventh Fleets must be brought into a major battle, or
attacked destroyed piece by piece. Gain Operational Superiority around Hawaiian Islands. Mobilize all reserve components, increase recruitment
quotas.
Phase 2 - "Liberate" Hawaii, elements of Hawaiian population that opposed US rule having been armed by Sangese Intelligence Agency prior to war, would
be given a "Greenlight" to launch a major uprising to disrupt US ground forces. Sangese Fleets will battle Third and/or Seventh Fleet task forces (if
any left). Defeat US airforce, avoid destruction of any airfields if possible. Ground Invasion to strike harbors, air drops units in and around
airfields and command centers. Land amphibious tanks to support infantry. Avoid major population areas and focus on military targets. Once US
Forces overcome, follow through in supporting a new state of Hawaii. Formally request (but firmly remind who is incharge) use of all military
installations from the New Hawaiian government.
Phase 3 - Slow momentum, Focus on bringing Hawaii facilities back to adequate use. Consolidate Unit losses from fleet and army/marine forces. Set
up supply lines back to homeland, attack and subdue any Island nation that refuses to give port access from hawaii to homeland. Continue to seek and
destroy Third/Seventh US Fleets. Deploy submarine forces to Bering strait, Drake Passage, and west Panama coast. Identify US West Coast Military
Targets. Identify all Alaskan Oil, Mineral, and Timber resources, their locations, quantity and quality. Identify Mexican drug cartels who are
"friendly" to Sangese Intelligence Agency. Increase arm smuggling to mexican drug cartels, in return for continual disruption of Mexican Military
and government. In return for "safe" landing sites along Baja California peninsula.
Phase 4 - Probe West coast defenses with two fleets. Launch invasion of Alaska, gain air superiority, subdue airforces, strike all military
installations through incremental levels of threat priority. Primary objective is to take all natural resource deposits and facilities intact.
Once all goals have been met. Bring in occupational forces.
Rotate "Veteran" units in a time table to homeland. muster army and air forces for the invasion of California, Oregon, and Washington.
Phase 5 - Invade the continental United States from the west coast. Defeat and subdue US Fleet. Gain Air Superiority from Coast to 150 miles inland
of US Coast. Begin bombing campaign once Air superiority achieved. Targets include missile silos, military bases (primarily barracks). Commence
Division sized amphibious landings at the following locations: Grays Harbor, Washington; Willapa Bay, Washington; Astorias, Oregon: Tillamook Bay;
Oregon; Winchester Bay, Oregon; Coos Bay, Oregon; Pelican Bay (Tolawa state park), California; Humboldt Bay, California
San Fransico Bay Area will be attacked from multiple directions. Airborne Divisions deployed to Santa Rosa, Petaluma, Fair Field, and Livermore.
These will cut off major high ways from the north and east of the bay.
Brigade strength amphibious landings in Monterey Bay at Santa Cruz, Watsonville and Monterey. Again Brigade strength landings at the following
locations; Stinson Beach, Moss Beach, Half Moon bay. Utilize amphibious assault ships to land multiple brigade strength units at san franciso
international airport, Almeda, Richmond.
Sangese Navy will target enemy forces in the cities with missile strikes, civilian losses "acceptable" plead human shields are in use to UN Security
Council.
Thus in response to the original post, I would like to say this is how I would conduct an invasion of the United States. Overall goal is to quickly
neutralize the US Military, deprive it of resources, and with out using nuclear weapons. More than likely NATO forces would be deployed on US soil,
and a war "Front" would eventually appear along the rocky mountains if all goes according plan!
PS: I might post an update to this later on, concerning Southern California/Baja California invasions, but of course you can imagine what that would
be like fighting over LA and San Diego/Tijuana.
