Putin losing

A couple of weeks into the Ukraine war some suggested that the West did not want Putin to lose for fear he would resort to nukes. Now some of those fears are confirmed as the question keeps coming up as to where are the weapons. Why is it taking so long to get missiles to Ukraine. The US says they are sending weapons and Zelensky keeps saying he is not getting the weapons he needs. Is this a problem of communication and if so what is being done to correct. He was promised the bigger Javelins two weeks ago and still doesn't have them. Which story is true. Looks like Putin's new plan is to take part of Ukraine and then ask for a cease fire and negotiate to retain some of the land and Zelensky wants no part of that. To push the Russians out Zelensky needs more weapons. Does the West want to push the Russians out and allow no way for Putin to save face. These are important questions that must be answered otherwise confusion reigns.
