This Andreas Antonopoulos interview about a government-financed 51% attack was (at least) 10 years ago. The Bitcoin hashrate in that time was around 718 PH/s. Nowadays, it is around 939 EH/s. That’s ≈ 1300x times more computing power. They couldn’t attack Bitcoin then. They can’t attack Bitcoin now (1300x harder).
