Yes that is the reality isnt it?
How would China start a war with us?
1st. Do as you stated. Insert a bio weapon within the enemy country.
2nd. Infiltrate and start civil unrest within that country.
3rd. Be aggressive by claiming territory and use security as an excuse.
4th. Quiet down your friends and have them prepare to start the conflict.
5th. Cyber warfare.
6th. Go for the win before you have to go to war. By using the enemies political system by using that systems greed and immorality to gain control.
7th. If the political thing fails. Then attack. By using your infiltrators to attack within that country. Remember that 911 just 19, or so, nearly brought this country to its knees.
8th. Bring the war by spreading the battle field out over a wide area of the globe.
9th. Go to war to take your populations minds off the disasters and problems at home. Blame the enemy for all of it through the use of false narratives. I.E. Global Warming.
10th. Destroy your enemies infrastructure. I.E. the Panama Canal, Ports..etc. They have already damaged the air service through the Bio Weapon.
How many of these have happened so far?
How would I-if I were a Chicom start the battle?
The infiltrators are here. Have them attack the strategic areas. Start forest fires, Pipelines, Rail systems. Ports Airports..etc. Massive riots and sniping within the strategic cities-Seattle, LA, Long Beach, San Diego, San Fran..etc.
Use the southern border. Send up armed militia through the southern border. Gain complete control over the Panama canal-they already own ports on both ends and own many ports within this country. Use the friendly south American countries to do as much mischief as they can.
Have N Korea attack south. While we are involved there, attack in the South China sea. Get a conflict going in the Islamic Countries and Africa. Move on Taiwan. Destroy the US Military bases in the Pacific.
Will they invade the USA? Depends on how many/much they have salted into Central America.
How can they supply? Depends on how much they have salted into Central America. As for food, they eat everything.
Remember this-neither the Red Chinese nor the Islamic Countries care for their population.
