globalization evolves continuously, nations have a
closer relationship with each other than ever and they
share common interests on a growing number of
issues, including the space arena. If confrontation in
space happens, the loss will be beyond the
imagination and no nation will be exempt from the
loss. Hence, nations should avoid setting a space
strategy with a militarized mindset, instead, being
open and inclusive is an excellent alternative. As one
of the most powerful nations in space, the U.S. is
expected to play a leading role in maintaining space
security. Faced with the potential challenges and
risks, the Cold War mentality is not feasible any
longer. The U.S. should work with other major
powers to optimize the space security environment.
When problems emerge, each party has the obligation
to insist on the basic principle of win-win cooperation
and establish robust diplomatic exchanges for
peaceful solutions. For example, to prevent
misunderstanding as well as confrontation, the United
States can improve the dialogue mechanism with
nations like China and Russia, discussing “bright
lines” in space, and mutual assurance measures
(Kello, 2022).
6 CONCLUSION
This article takes the space policy under the Trump
administration as the research object, focusing on the
deep logic of the U.S. space strategy and the real
impact on international security. Through the analysis
of policy texts, the space policy of Trump’s first
Administration has three characteristics: broader and
deeper space exploration, space commercialization
and space militarization. Such characters are driven
by multiple factors, including being consistent with
former U.S. space strategy, reviving U.S. economy,
and pursing hegemony in the space field. Then the
article further shows that Trump’s space policy
results in challenges to other nations and international
security. The U.S. is hostile to emerging spacefaring
nations, so their space capability is deliberately
suppressed. For the EU countries, cautious options
remain to be made between autonomy and national
security. In the worldwide, aggravation of Security
Dilemma and space arms race emerge. In terms of the
risk of a disordered space governance system,
international society is encouraged to make joint
efforts to improve the international law on space,
enhance international space cooperation and space
resource sharing, and adhere to the concept of
peaceful development and a shared future for space.
