TEMPORAL SUBJECTS AND SCHEDULING DEPARTMENT
HAIMBOURGHA, TRIUMVIRATE OF YUT RESERVED REGION, TITAN
In light of the recent public and political interest in the concept of temporal weaponry, we've been authorized to declassify the general results of our theoretical research into the potential and probable counters to such technology. This research was performed in conjunction with the Scolopendran Office of Psionic Operations (SOPO) and the Triumvirate of Yut metanormal defense force HELLSING with the intent of determining the potential threats of the 'temporal weaponry' boasted by certain foreign powers, if these threats required addressing, and if so, probable counters to them. Thus, this summary is a declassified executive-level report on the broad results of these analyses, without going into technical or operational specifics. It is hoped that greater public knowledge of the science behind these systems will fortify them against the--in our opinion--mostly paranoiac descriptions of them being bandied about publicly.

1) CHANGING HISTORY/THE PRESENTThe greatest concern to most regarding the potential weaponization of time travel and related technologies is the ability to go back and change time. After much research in this area, it is the official position of TimeWANCC that this is a non-threat for the following logical reasoning, [STATEMENT REDACTED]:
(a) Hypothesis: our current timeline is static; objectively, what has happened has happened and it cannot change. Only our understanding of history, via new discoveries, changes.
(b) Posited: if time travel technology is possible, then it is theoretically available to all time travelers in the past and future, relative to any given point in time like the present.
(c) It follows from (b): there are a finite number of possible time travelers from the past, but a relatively infinite number of possible time travelers from the future (with obvious hard limitations due to the heat death of the universe).
(d) Known: any time traveling to the past must, in relation to the present, have occurred in the past. This means that the events of the traveling predate the present.
(e) It follows from (c) and (d): there have been an extremely large number (ELN) of time traveling events in our own past.
(f) It is currently known: no events in our history are dependent upon time travelers.
(g) Known: we continue to exist in continuum from moment to moment and have not been unmade due to alterations in chronology, which would occur due to the very process of time travel (see chaos theory re: chain of events).
(h) It follows from (e), (f), and (g): there have been an ELN of time travelers heading to our past, but there has been no effect indicative of such a thing as would be required by (g).
(i)Therefore: time travel logically has no effect on the past in such a way that the present is effected. Since only one kind of past can result in our known present (see chaos theory re: chain of events), time travel must have no effect on our perceived past and actual present.
(j) Therefore: our current timeline is static; objectively, what has happened has happened and cannot change.
Quod Erat Demonstrandum.
Perhaps the greatest evidence for this logic is the fact that every unpopular person (especially oppressive and genocidal dictators) in history still exist in history, since they weren't preemptively assassinated by forewarned time travelers with high-powered rifles.
2) PREDICTING THE FUTURE
Since any time traveler would be observing a future they technically played no role in, as the time horizon of the prediction increases, chain-of-event chaos theory becomes more and more dominant. Returning to the present and acting on these predictions would also inevitably change to some degree the events predicted, putting predictions past those events in jeopardy. While there could be real application for this technology in terms of predicting natural disasters or learning about currently-classified technologies by moving forward to when they are declassified, this does not present an immediate threat and can be relegated to the research and intelligence communities.
3) TEMPORAL LOOPS AND PARADOXES
See Item 1) above. The inability to change the past makes the possibility of the famed "Grandfather Paradox" inherently impossible.
