That's precisely the point, isn't it?
"We will put an end to X" does not mean "we will physically blow up X". Pretending Biden had an "oops, we're gonna do a terrorist attack against Russian and German infrastructure and I said it out loud at a press conference!" moment and that there's no other legitimate explanation for the statement is just goofy.

Again, "we'll bankrupt them with sanctions" easily falls under "we will put an end to them".
Conveniently for Russia, Nord Stream 2 still exists. Only one of its two pipes had exploded. Everyone forgets about it.
