He said "I take full responsibility for the decisions that led us here"
You can argue about the semantics of "responsibility" means, but i think in context he's basically saying "my bad". Nothing more nothing less.
If you look at the dictionary definition https://www.merriam-webster.com/dictionary/responsible this way of using it is consistent. "being the cause or explanation" is one of the definitions. Sure there are other meanings to the word, but this is the one that makes the most sense in context even if you wish he meant the other one.
