If other countries in middle east are involve in fresh war then it's possible that the price of oil will increase but if Iran and US should continue their battle, the pump price wouldn't make any difference. I don't know what's happening in the global oil market but the pump price of oil here has only been reduced by less than few cents, I'm not sure if they are waiting for the old stock to finish so they can make fresh stock at low price, nothing has changed.
The peace between Iran and US has not been fruitful, the US are making demands to subject Iran to hard labour on their money that was seized, they want them to spend their money on their farmers and I'm like who gave them this useless advice. First, the money belongs to Iran and was never gotten under any form of practice, why give them conditions to spend the money and you want peace. Sometimes I feel Trump want to make even peace a strategy to think he is the king that has a say.
Trump thought his "Venezuela strategy" was going to work in Iran. Turns out, he was wrong. Because Iran is more resilient than Venezuela itself. Some say the real intentions behind the war was to acquire all of Iran's oil. They may be right, especially when Trump floated the idea of deploying ground troops on Kharg Island (which is Iran's economic lifeline, btw).
The world is now paying the price of a prolonged war. Even with an agreement in place, that's no guarantee there will be permanent peace. The deal is a fragile one. Recently, Iran targeted another vessel in the Strait of Hormuz. So you can see where this is all heading to. Wishing everyone the best of luck.
