It would be tough for Israel or the US to achieve their aim without a war cause Iran won't back down on their project they've been on it for years and spent billions to try be among the nuclear war heads so Trump can't dictate for them concerning that, not at this point, and not forcefully, I know they're scared that Iran might use it against their neighbors (Israel) if they succeed in producing more nukes, maybe for a retaliation for killing the Hezbollah and Hamas generals, and making several Palestinians homeless, but destroying Iran's facilities, killing scientists, and those generals wasn't a good way to go about it cause the result was a retaliation by Iran and further destruction from both parties. What the world need is peace wars causes death and destruction and the innocent people suffer the most while war mongers would still continue to live afterwards.
Sure, I share in your view. War is a barbaric way of settling dispute, because the strong will always impose their will on the weak. And it also shows that the leaders are only interested in their own personal and selfish interests without considerating their citizens which is meant to be their responsibility. It only shows that they really don't care about them and they'll be willing to put them into harm's way just to achieve their aim, and this is a very barbaric way of thinking, and we should've outgrown this mindset and sort for more amicable way of resolving conflicts such as this
