For those who have not been following the news. Saudi Arabia's intervention in Yemen was meant to defeat the uprising by Houthis and Saleh's forces. The Houthis were allegedly backed by Iran. The previous president, Ali Abdullah Saleh, gave up power to Abdrabbuh Mansur Hadi during the Arab uprising. Hadi was backed by Saudi Arabia and was ousted from power following the 2015 popular uprising by combined forces of Houthi militias and Saleh loyalists, which took place due to dissatisfaction with Hadi's government.
following Hadi's departure and his escape to Saudi Arabia, Saudi Arabia attempted to rally the Arab world to intervene and defeat Saleh and the Houthi forces in a US-like military campaign. Iran was used as the boogeyman to scare arab nations to lend aid to Saudi Arabia's campaign. This coalition managed to stop the government from falling apart, but at a great cost.
now, about 4 years later, Saudi Arabia is locked in a quagmire and is growing ever more isolated in it's campaign. The Houthis, after executing Saleh and taking over his remaining forces, managed to dig in and hold their positions west of Yemen. But a few weeks ago something peculiar happened. The UAE held a security meeting with Iranian officials following an announcement by UAE to pull back half of their forces (most of which are foreign mercenaries) from Yemen which effectively left Saudi Arabia alone to lead the civil war.
and now, only a few days ago this happened.

Apparently the UAE-backed separatist forces took control of Aden after fighting and defeating Saudi-backed government forces. So it seems that this so-called coalition has descended into a civil war itself, With UAE emerging victorious. It appears that Saudi Arabia's campaign, after 4 years of bloodshed which created a humanitarian catastrophe, is about to end in utter disaster.
What does that mean for the region? the intervention was meant to mark Saudi Arabia's rise as a regional power-player and ensure regional allies that following America's partial departure from the Middle East (which is gradually happening) Saudi Arabia can be relied on to carry out military operations and ensure that the western backed regional hegemony stays intact. The disaster that was the Yemen Civil war, alongside the events that happened in Syria and Iraq, are showing the exact opposite: that Saudi Arabia and it's allies cannot be relied on to hold their own against Iran's growing influence in the region.
Saudi Arabia has gradually lost it's allies following their radical and bold decisions towards their neighbors. They led a blockade against Qatar which did not do much to bring Qatar back into the fold but served to move Qatar from the coalition even further towards Iran and Turkey, They held Lebanon's prime minister hostage hoping that it will get Lebanon to switch sides only to have the french president intervene and free the official (which ironically served to prove Iran's point that Hariri is just a Saudi puppet), They lost Egypt and Pakistan's support in their Yemen war, and finally they have fallen out of favor in US following the death of the Saudi journalist Khashoggi, with many US lawmakers truly questioning whether or not Saudi Arabians can be considered allies after their dismal record of human rights violation.
This has been in the work for some years now, the sudden escalation between the US and Iran also boils down to US' fears that Iran is on it's way to topple Saudi Arabia's hegemony in the region. This hegemony however was never truly created by SA though, they are just taking over America's role. This recent escalation and war of words was not really about Iran obtaining nukes or Iran being anti-Israeli, It is about Iran becoming a regional power-player that can dominate the region which to Iran sounds even better than obtaining nukes. (which was meant to serve as a deterrent force to begin with) Iranian authorities are aware that USA does not want a full-scale war, which is why they have grown bold and sure of their actions as of late.
Why is this important though? With the UAE-backed forces taking over Yemen and the UAE trying to reach out to Iran, It appears that UAE is seriously considering leaving the SA-backed coalition and focus more on it's national interests. This would tilt the balance of region further towards Iran, with UAE breaking ranks Saudi Arabia might actually be left truly alone in the region in it's goal to mimic America's influence.
