At the beginning of 2025, the US was only supplying 20% of the military aid to ukraine.

After that it has practically completely dried up. Ukraine and the EU are already producing themselves.

This is a big long term loss to the US.

Also if US makes their LNG unaffordable the EU will simply switch to countries like India.

Who exactly is the US going to still sell to?

India is LNG importer, not LNG exporter.
