It is doable, given sufficient political will, though it’d be militarily pointless to go that far. Russia would fold long before that, or try playing nuclear hardball or something.
In 1943 and 1944, more than 40% of GDP was devoted to national defense.
US estimated GDP for 2024 is $28.781 trillion.
That’d be about $11.5 trillion/year for military spending, were things to reach WW2-comparable levels.
The EU estimated GDP is only up on WP for 2023, but that’s $17.818 trillion. Add that to the UK’s 2024 GDP of $3.495 trillion, Canada’s estimated 2024 GDP of $2.242 trillion, Japan’s estimated 2024 GDP of $4.110 trillion, Australia at $1.790 trillion, Turkey at $1.114 trillion, and Norway at $0.525 trillion, and you’ve got another $31.094 trillion in aggregate.
40% of that for military spending would be $12.438 trillion/year.
So at that kind of level, figure $24 trillion a year to work with as the aggregate of the US and all other listed countries.
