There is little thought of helping others, and instead the focus is on providing their army with the best possible technology. There were elements during the earlier parts of the series where the Soviet test base had the air of a clandestine operation, with various secrets that they are willing to torture and kill in order to protect. The latest arc has demonstrated that it is the Soviet Union (we can only assume that in the Muv-Luv universe the Iron Curtain never truly fell, this the continued presence of the Soviet Union rather than Russia) who is attempting to maintain a strong military presence. Or at least this is the message that certain countries and groups are sending out during this series.
Those who have the largest and most experienced military force with the best technology will ultimately rule the world. Every major country and military power is attempting to design and build the best and most powerful weapons possible, not for the good of humanity, but for their own military and political aims.
Quite the opposite has happened with a similar arms race to the ones before WWI and WWII along with the Cold War in full flow despite this threat.
The BETA may be a significant and ever present threat within the Muv-Luv universe, but it has not brought all countries together. The most recent arc of Muv-Luv Alternative – Total Eclipse has brought to light some interesting but obvious problems with the Muv-Luv universe, and humanities attempt to beat the BETA.
