Russian Bounty on US Soldiers...and Trump’s known for months...
The "cash" was the rightfully property of the Iranian government that America "froze" in Western banks after the embassy hostage taking and regime change in the late 70's - it was part of the nuclear deal that the Trump Administration later refused to honor!
A better question would be as to why this President has chosen not to freeze the accounts and assets of the Russian government and its oligarchs in retaliation for Putin putting a bounty on the lives of American soldiers?
It is well known the Russian billionaires have a long history of laundering their money by purchasing real estate and other assets in the West - a safeguard against having to make a quick exit should the political climate in that country suddenly turn against them!
