I'll try to predict what will happen in this war:
First,
red feel very confident of winning the war and
blue takes it as their advantage. They start working together with
yellow. Blue send almost all of their manpower to start an attack to
red's base,
red respond by sending dozens of units to defend the border but it failed miserably.
Blue also send some of their manpower to start an offensive attack towards
pink. because of
blue's manpower superiority,
pink cannot stop the attack and surrenders. Meanwhile on the other side,
blue successfully penetrated
red's defenses and continue pushing towards their base, and not long after that they changed plan and start another offensive to the southern part of
red to take over
red's big city and oilfields.
Yellow on the other side, they tried to expand their territory by starting an offensive attack towards
purple.
Purple respond by sending dozens of troops to defend their border, and because of
purple's defence outmatched
yellow,
yellow failed to take over the border.
Because
yellow and
blue are allies,
purple start an offensive attack towards
blue.
Blue see the issue and respond by sending half of their manpower that were focused to attack
red's base and city to defend blue's border from
purple.
Red takes it as their advantage, they start a massive flanking attack towards
blue's units and surround the city. Because of
blue's manpower were cut half,
red outnumbered
blue and pushed back their offensive attack.
Blue got outnumbered too on their defence against
purple and that leaves
blue to a defensive position against purple and red. Red continues pushing towards
blue's territory,
blue once again tried to defend the line from
red but they got outnumbered. The
red army and
purple's offensive units keeps pushing forward until they reached
blue's base.
Red got into
blue's base first and they take over the main building.
Blue see it as their defeat and surrenders.
Red celebrates their victory and
purple stopped their offensive attack. After
purple stopped their attack, they stumbled into
red's territory and they meet with each other on a river.
Red army welcomes them and they even take a photo at the broken bridge.
Just to be clear, this reply is a joke
