What is the Summary of the steps that Axis powers took to achieve world power prior to WWI?

I assume that you mean WWII and not WWI, since the Axis
powers are a WWII thing.

In general, what the Axis did was
that Germany rearmed and started to expand while Japan continued to build its military
and to try to expand in China.

The Treaty of Versailles had
badly weakened Germany and had essentially destroyed its military.  Germany, under
Hitler, started working to remake the military.  It also took Austria and
Czechoslovakia.  Finally, it made peace with the USSR as a way to secure its eastern
flank.

Japan was on the winning side in WWI so it did not
have to disarm and it got various German possessions.  It tried to expand its influence
in China during the 1930s.
