Yes, they can topple small nations (though not really, it never actually happened), that’s what they have been designed to do, to work as the XX-XXI century gunboat diplomacy, not to actually strike alone but to make terror threats of destruction.
But their usefulness is currently around zero in a peer combat against Russia or China, hypersonic missiles are hard counter for them. And note that US is even reluctant to post them nearby Iran because Iran also have some dangerous to them weapons like supercavitating torpedoes.
US Navy surface fleet is therefore pretty vulnerable to PLAN which got close to force parity in defence scenario, but nearly all PLAN ships are more modern and will have advantage in defense because being on the other side of Pacific.
So the only real and big advantage US Navy have is their submarine fleet which is much bigger than Chinese and make exclusively of nuclear submarines which in itself is advantage especially on area as huge as Pacific. No wonder China put some serious money and brainpower to this research.
US Navy surface fleet is therefore pretty vulnerable to PLAN which got close to force parity in defence scenario, but nearly all PLAN ships are more modern and will have advantage in defense because being on the other side of Pacific.
Also consider that in a fight with China over Taiwan or the West Pacific the US surface fleet will have to also deal with shore based aviation and ballistic missiles.
The old adage that a ship should never try to fight a shore battery probably holds true to this day.
