It would be an interesting hypothesis to study....what if the refineries in the TX area were destroyed and no hope of any out for a minimum of one year or more.

Seems to me I read some where that it takes 10 years to build a refinery (??)....

Here was the concern in 2005;

No New Refineries in 29 Years? There Might Well Be a Reason - The New York Times

What has been done since?

The catastrophic events that interrupt steady state America should be wake up calls to those who govern our states and country.

But they are not.
The America as we know it is running on an antiquated infrastructure, power grid, supply system et al.

The politicians ....if they were firemen......would wait until the until they actually see the flames before doing anything......better known as too late.....just like all our other vulnerabilities.
