Maybe because we’ve been one of their biggest suppliers since before Russia invaded and we have the largest military spending budget of any other country.
Other allied countries are providing aid, I don’t understand why we need to moderate our giving with other countries when we have more resources to go around + have a vested national security interest in Putin not expanding territory or influence.
This isn’t the playground, if we can do more we should, irrespective of the capabilities of others. That’s the responsibility that comes with being a global superpower.
