Maybe this: [AB[C]]DEFGHIJKLM .
is saying that Q/Trump are going after GOOG next. GOOG is a subsidiary of ALPHABET INC.
Also, looking at the exact post from Q, after M there are two ellipses, then a period. An ellipsis is 3 dots.
So 7 total dots.
So [AB[C]]DEFGHIJKLM331
or
[AB[C]]DEFGHIJKLM NOP QRS T
or
[AB[C]]DEFGHIJKLM NOP QRS.
or something similar?
Ot maybe it means nothing..............
