Special Military Operation done right.
Do you really think killing Zelensky will have any effect on the war? Can Russia achieve any of their goals by doing so?
Simliiarly do you think killing Lai would lead Taiwan to unify peacefully?
This applies to Venezuela too, the US's actual goal, and this is not necessarily Trump's goal, is to install a puppet government and hand over Venezuela's oil to the US. Maduro isn't the only person in the way of that, and one tend to not become more favourable among the people when you're openly allied with a foreign country who just launched an unprovoked attack on your soil.
On the other hand if US actually need to physically occupy Venezuela to control their oil, it'll become a quagmire just like Iraq and end up with a government that, like Iraq, will just sell oil to China anyway.
Maduro had plenty of warning to move to a bunker outside the capital and make it impossible to get to without a large scale ground operation, and US could have left him to last if the goal is to occupy the country. Just like bombing Iran's empty IAEA insepcted "nuclear weapons facility" and calling it a day, the choices made looks more like an off-ramp for both sides than a serious attempt at achieving the greater agenda. After all Maduro is a propaganda item for a greater agenda but not really the point, to make him the main point suites Trump's personal goal of appearances but by itself doesn't actually advance the greater goal, if not actually counter productive.
Putin's goal in Ukraine isn't to score domestic political points, if he bombed Kiev and killed Zelensky on day 1 then called it a day, it would be a disaster for Russia's security enviroment. At this point either Trump has to commit to a full occupation, or he just f*ed up.
