The West Coast states withdraw from the US.
They no longer have access to federal funds or services.
A few of the true communists are gleeful.
Now, they can invite in the Chinese.
The Chinese come in.
That part of the ocean becomes known as The Bloody Pacific as the Chinese eliminate all westerners.
Anyone think that’s something worth having?
Thomas Jefferson’s Louisiana Purchase and James Polks’ vision of manifest destiny was the correct geopolitical vision for the US. Control of the west coast and the Mississippi basin to New Orleans is key to national security.
How do we control the Pacific without the west coast. As Jefferson recognized (about the Louisiana Purchase), as soon as the US does not control the land to its west and access to the seas, we become dependent on alliances with European powers (today Asian and/or European powers) to protect us.
Control of access to the Mississippi basin was the main reason the North opposed Southern Secession.
