Even without any sign of war, recent months have seen a number of countries either ban, or attempt to tax, food exports in an attempt to safeguard supplies for the local population.

Americans now save more than 5% of their after-tax income, still well below the post-war average but hugely up from only a year ago.

I do have a problem with my tax dollars going to fund an unnecessary war that is costing us trillions of dollars and costing so many lives.
