A moral issue

There are those who want the U.S. to continue funding U.S. support for Ukraine.

Where do those funds come from?

The USG currently runs a very sizable deficit.

That means the USG has to sell bonds to finance its activities.

And on whom falls the obligation to repay the bondholders?

By and large, not the current generation, but later generations.

I.e., we are putting future generations deeper and deeper in debt.

Should we put future generations in debt to finance Ukraine's resistance to Russia?

I think absolutely not.

That is the correct way to think about U.S. support for Ukraine, IMO.

The important point is:

what are the country's vital needs?

("The country" being the USA.)

Surely support for Ukraine is not one of them.
