Buzz Aldrin has said that NASA should stop spending $3.5 billion per year on the International Space Station and relinquish low Earth orbit activities to private companies, such as SpaceX, Orbital ATK, Boeing, Bigelow Aerospace, and Axiom Space. This would allow for the funding of "cyclers" to enable a base on the moon and eventually a permanent presence on Mars:

Establishing private outposts in LEO is just the first step in Aldrin's plan for Mars colonization, which depends heavily on "cyclers" — spacecraft that move continuously between two cosmic destinations, efficiently delivering people and cargo back and forth. "The foundation of human transportation is the cycler," the 87-year-old former astronaut said. "Very rugged, so it'll last 30 years or so; no external moving parts."
Step two involves the international spaceflight community coming together to build cyclers that ply cislunar space, taking people on trips to the moon and back. Such spacecraft, and the activities they enable, would allow the construction of a crewed lunar base, where humanity could learn and test the techniques required for Mars colonization, such as how to manufacture propellant from local resources, Aldrin said. Then would come Earth-Mars cyclers, which Aldrin described as "an evolutionary development" of the prior cyclers.
[...] NASA officials have repeatedly said that the ISS is a key part of the agency's "Journey to Mars" vision, which aims to get astronauts to the vicinity of the Red Planet sometime in the 2030s.
Is the ISS a key part of the "Journey to Mars" or a key roadblock?

In FY 2015, Pentagon and related spending totaled $598 billion, about 54% of the fiscal year 2015 U.S. discretionary budget. For FY 2017, President Obama proposed the base budget of $523.9 billion, which includes an increase of $2.2 billion over the FY 2016 enacted budget of $521.7 billion. By 20 January 2017, when President Trump took office, annual military spending had reached its highest peak ever—$596 billion—representing three times the military spending of all other NATO countries combined.[1]
FY2017 19,508 Nominal Dollars (Millions) % of Fed Budget 0.47%
Seen in the year-by-year breakdown listed below, the total amounts (in nominal dollars) that NASA has been budgeted from 1958 to 2011 amounts to $526.178 billion—an average of $9.928 billion per year.
So the amount of money spent on NASA for its entire existence since 1958 just barely edged past what we spent on the military in a single year under Obama. After 59 years. Marvelous.
