Maybe he believed it, maybe not.
My take is that Bush was trying to sell the WMD bullshit so hard he wouldn’t be above telling allies that he could make flying monkeys shoot out of his ass if he thought that it would get him any support for his war to enrich defense contractors.
It really depends on where the office is in relation to your home.
Before covid and going WFH, the office was only 5 miles away on roads with no traffic. I would go back to this, no problem. Just enough to keep you on a schedule and get out of the house.
The biggest benefit of an office is that when you leave, you are gone until tomorrow.
When everyone is WFH, you never completely leave the office. I know boundaries, but in many cases, the lines can get a bit fuzzy.
