Yes, I think so. Australia is often drawn upon, because it's very similar, as well as the United Kingdom. The U.S. is a bit harder, because their system of government—as you know—is different.
However, with respect to the United States, the main thing this will accomplish is that it will suggest to them, quite forcefully, that Parliament is taking this very seriously. Simply the creation of crimes and potential penalties of up to life imprisonment sends a pretty powerful message that the country is annoyed.
I think it's mostly the U.K. and Australia, but the United States will likely be pleased we're going down this path.
