Production of shells in the West is not something that they-especially the Americans can increase. That's because they are produced by PRIVATE companies, with fixed number of personnel and specialists, fixed range of machinery, fixed investments. It's not possible for them to increase any of them without getting a long-long term contract.They just produce a steady output to replenish expired munitions, while all armies keep stocks for emergencies/wars enough to last for about one month.
The cluster bombs the Americans have in stock are from the 80s -90s. Their shelf life is maximum 20 years, so they are all expired. Imagine how many of them will ever detonate and how many will kill civilians later over the years. Furthermore these bombs are "area munitions" designed to clean up a region of attacking army, therefore they are totally unsuitable for the Ukrainian offensive (no matter how much of a joke that offensive already is). And of course it will untie the hands of the Russians to start using their own cluster bombs, which contrary to the old Western technology, they self detonate within a few days in case they fail on impact.
Notice Sleeping Joe said "we will supply the Ukrs with Cluster bombs-just temporarily- until we get fresh supplies of normal bombs". He did not specify when exactly this will happen though.
And as we all know there is nothing more PERMANENT than TEMPORARY.
True the West got used to fight wars against people who can't defend themselves. We all still remember how they were bombing poor people's wedding parties is the middle East...
Before this war in Ukraine I didn't really pay much attention to what the West and especially the Americans were doing. Watching them now, makes me feel disgusting and embarrassed living among these Western pussies. And it's not only them, the Israelis themselves are a case of their own.
