Before this, it was essential to keep the Iraqi troops outside the gates of Saudi Arabia.
That is to say, a defensive line needed to be constructed to the north of Saudi Arabia to ensure the safety of oil fields located in the northeast, near Boss Bay.
To put it bluntly, the bottom line for the Empire was that the oil fields in Saudi Arabia and other oil-producing countries in Boss Bay would not be threatened.
Although more than 40 years had passed since the Second Global War had ended, the Empire was still the leading oil-consuming and importing country in the world.
For decades, everything the Empire had done in Boss Bay was, without exception, aimed at ensuring the supply of oil and safeguarding national energy security.
In the words of the outside world, "the Third Global War will commence the day after the Empire is driven out of Boss Bay."
This was also the reason Liu Zunshan was sent to Saudi Arabia.
